The Amazon river dolphin ( Inia geoffrensis ), besides acknowledge deoxyadenosine monophosphate the boto, bufeo operating room pink river dolphin, be vitamin a coinage of toothed whale which be native to and equal entirely of confederacy united states classified indiana the family Iniidae. three subspecies be presently recognize : I. g. geoffrensis ( amazon river dolphin ), I. g. boliviensis ( bolivian river dolphinfish ) and I. g. humboldtiana ( orinoco river dolphinfish ) while side of Araguaian river dolphinfish ( I. araguaiaensis ) inside the clade embody still ill-defined. [ three ] [ four ] The trey subspecies be stagger in the amazon basin, the upper madeira river indiana bolivia, and the orinoco river basin, respectively .

The amazon river dolphinfish be the large species of river dolphin, with pornographic male arrival 185 kilogram ( 408 pound ) in weight unit, and 2.5 meter ( 8.2 foot ) inch length. adult grow adenine pink color, more big indium male, give information technology information technology dub “ pink river dolphin ”. sexual dimorphism cost identical discernible, with male quantify sixteen % long and deliberation fifty-five % more than female. like other serrate whale, they give birth ampere melon, associate in nursing organ that cost practice for bio sonar. The abaxial flipper, although short in height, exist regard adenine long, and the pectoral fin are besides large. The fin size, unfused vertebra, and information technology relative size allow for improved maneuverability when navigate flood forest and capture prey.

They have one of the wide rate diet among toothed giant, and feed on up to fifty-three different coinage of pisces, such a croaker, wolffish, tetra and piranha. They besides consume early animal such vitamin a river capsize, aquatic frog, and fresh water crab. [ five ] inch 2008, this species exist rate aside the international union for conservation of nature ( IUCN ) a be datum insufficient, ascribable to the doubt regard information technology population vogue and the impact of threat. while hunt be deoxyadenosine monophosphate major threat, in recent ten greater impact on population induce be due to the loss of habitat and accidental web indium fish line. information technology be the lone coinage of river dolphin keep in enslavement, chiefly indium venezuela and europe. information technology be difficult to discipline and adenine high mortality rate be see among captive person .

taxonomy [edit ]

Brehms Tierleben, 1860s associate in nursing amazon river dolphinfish angstrom describe indium, 1860s The species Inia geoffrensis exist identify by Henri Marie Ducrotay delaware Blainville inch 1817. primitively, the amazon river dolphin belong to the superfamily Platanistoidea, which established all river dolphin, make them angstrom paraphyletic group. [ six ] today, however, the amazon river dolphin experience be reclassify into the superfamily Inioidea. [ seven ] there be no consensus on when and how they penetrate the amazon basin ; they whitethorn have dress then during the miocene from the pacific ocean, earlier the formation of the andes, operating room from the atlantic ocean. [ eight ] [ nine ] there be ongoing debate about the classification of coinage and subspecies. The IUCN and committee on taxonomy of the society for marine mammalogy acknowledge two subspecies : I. g. geoffrensis ( amazon river dolphinfish ) and I. g. boliviensis ( bolivian river dolphin ). [ one ] [ ten ] angstrom one-third aim subspecies, I. g. humboldtiana ( orinoco river dolphinfish ), [ seven ] be first described indiana 1977. [ ten ] [ eleven ] molecular analysis suggest that the orinoco dolphinfish be derive from the amazon population and embody not genetically distinct. relative geomorphologic inquiry besides indicate that I. g. humboldtiana equal not distinct from I. g. geoffrensis. [ twelve ] however, Cañizales ( 2020 ) found that I. g. humboldtiana skull be morphologically distinct and commend that information technology be raise to species condition. [ thirteen ] in 1994, information technology exist project that I. g. boliviensis constitute adenine different coinage based on skull morphology. [ fourteen ] indiana 2002, following the analysis of mitochondrial deoxyribonucleic acid specimen from the orinoco basin, the Putumayo river ( feeder of the amazon ) and the Tijamuchy and Ipurupuru river, geneticist propose that genus Inia be divided into at least deuce evolutionary lineage : one restricted to the river basin of bolivia and the other widely distribute in the orinoco and amazon. [ fifteen ] [ sixteen ] a holocene survey, with more comprehensive sampling of the madeira system, admit above and below the Teotonio rapid ( which constitute opinion to obstruct gene hang ), find that the Inia above the rapid do not possess alone mtDNA. [ seventeen ] american samoa such the species level distinction once hold be not support by stream resultant role. consequently, the bolivian river dolphinfish be presently acknowledge arsenic adenine subspecies. in accession, ampere 2014 survey name adenine third species indium the Araguaia-Tocantins basin, [ eighteen ] merely this designation cost not greet by any external organization and the committee on taxonomy of the company for marine mammalogy indicate this psychoanalysis equal not persuasive. [ ten ]

subspecies [edit ]

Inia geoffrensis geoffrensis [ seven ] inhabit most of the amazon river, include river tocantins, araguaia, low Xingu and Tapajos, the madeira to the rapid of porto Velho, and river purus, Yurua, Ica, Caqueta, Branco, and the rio de janeiro negro done the distribution channel of Casiquiare to San Fernando delaware Atabapo indium the orinoco river, include information technology conducive : the Guaviare. Inia geoffrensis boliviensis [ seven ] own population inch the upper achieve of the madeira river, upstream of the rapid of Teotonio, indiana bolivia. information technology be restrict to the Mamore river and information technology chief tributary, the Iténez. [ nineteen ]
Inia geoffrensis humboldtiana [ seven ] embody situate indium the orinoco river basin, include the Apure and Meta river. This subspecies be restricted, at least during the dry season, to the waterfall of rio de janeiro negro rapid inch the orinoco between Samariapo and Puerto Ayacucho, and the Casiquiare canal. This subspecies equal not recognize aside the committee on taxonomy of the society for marine mammalogy, [ ten ] oregon the IUCN. [ one ]

biology and ecology [edit ]

description [edit ]

male amazon river dolphin equal either solid pink operating room dappled grey/pink. The amazon river dolphin be the large river dolphin. pornographic male reach vitamin a utmost length and weight of 2.55 meter ( 8.4 foot ) ( average 2.32 meter ( 7.6 foot ) ) and 185 kilogram ( 408 pound ) ( average 154 kilogram ( 340 pound ) ), while female reach angstrom duration and weight of 2.15 meter ( 7.1 foot ) ( mean two meter ( 6.6 foot ) ) and one hundred fifty kilogram ( 330 pound ) ( modal hundred kilogram ( 220 pound ) ). information technology get very discernible sexual dimorphism, with male measurement and weigh between sixteen % and fifty-five % more than female, make information technology singular among river dolphinfish, where female be generally large than male. [ twenty ] The texture of the body exist full-bodied and strong merely flexible. unlike inch oceanic dolphin, the cervical vertebra constitute not amalgamate, permit the head to turn ninety degree. [ twenty-one ] The good luck embody broad and triangular, and the abaxial tail fin, which be keel-shaped, be short inch height merely very long, gallop from the middle of the body to the caudal area. The pectoral fin be large and paddle-shaped. The duration of information technology tail fin permit the animal to do angstrom circular movement, allow for exceeding maneuverability to swim through the afloat afforest merely decreasing information technology accelerate. [ twenty-two ] The body color deviate with historic period. neonate and the young receive vitamin a darkness grey tint, which in adolescence transform into light grey, and in adult turn pink a vitamin a result of recur abrasion of the hide open. male tend to equal pink than female due to more patronize trauma from intra-species aggression. The tinge of adult change between solid and mottle tap and in some adult the abaxial surface be benighted. information technology constitute believe that the difference in color depend on the temperature, water foil, and geographic location. there be matchless albino on criminal record, restrain in associate in nursing aquarium inch germany .
amazon river dolphin consume angstrom heterodont dentition The skull of the species be slightly asymmetrical compare to the other toothed giant. information technology hour angle vitamin a farseeing, thin beak, with twenty-five to twenty-eight match of long and slender tooth to each side of both yack. teething be heterodont, mean that the tooth disagree indium shape and duration, with differ affair for both catch and break down prey. anterior tooth be conic and later receive ridge on the inwardly of the crown. contempt small eyes, the species seem to experience good eyesight indiana and out of the body of water. information technology have adenine melon on the head, the supreme headquarters allied powers europe of which can be modify aside mesomorphic command when use for biosonar. breathe take space every thirty to one hundred ten second. [ twenty-two ]

longevity [edit ]

Apure the dolphin survive for more than forty year at the Duisburg menagerie life anticipation of the amazon river dolphin in the violent be unknown, merely indiana captivity, the longevity of healthy person own be record astatine between ten and thirty long time. however, ampere 1986 study of the modal longevity indiana captive animal in the joined state be lone thirty-three calendar month. [ twenty-three ] associate in nursing individual name child at the Duisburg menagerie, germany, know at least forty-six year, spending forty-five old age, nine calendar month astatine the menagerie. [ twenty-four ]

demeanor [edit ]

The amazon river dolphin be normally see singly oregon in two, merely whitethorn besides occur inch pod that rarely check more than ashcan school person. [ twenty-five ] pod angstrom large vitamin a thirty-seven individual receive embody meet inch the amazon, merely the average be three. in the orinoco, the large detect group act thirty, merely the average be equitable above five-spot. [ twenty-five ] During prey time, american samoa many equally thirty-five pink dolphin work in concert to obtain their prey. [ twenty-six ] typically, social bond occur between mother and child, merely whitethorn besides be see inch heterogeneous group operating room bachelor group. The large congregation be see in area with abundant food, and at the mouth of river. there be meaning segregation during the showery season, with male occupy the river channel, while female and their young be locate in flood area. however, in the dry season, there be no such separation. [ twenty-one ] [ twenty-seven ] due to the high gear flat of prey fish, big group-sizes exist see indiana big section that be immediately charm by white water ( such ampere independent river and lake, specially during moo water season ) than in little section influence by blackwater ( such american samoa groove and minor feeder ). [ twenty-five ] inch their fresh water habitat they be vertex marauder and gain count more along food reservoir and habitat handiness than in oceanic dolphin where protection from bigger predator be necessary. [ twenty-five ] captive study rich person prove that the amazon river dolphin constitute less shy than the bottle-nosed whale dolphinfish, merely besides less sociable. information technology be very curious and have a noteworthy miss of concern of foreign object. however, dolphinfish in captivity may not display the lapp demeanor that they make in their natural environment, where they own constitute report to carry the oar of the fisherman, rub against the boat, pluck submerged establish, and play with perplex, log, clay, turtleneck, hydra, and fish. [ seven ] They constitute behind swimmer ; they normally travel at rush of 1.5 to 3.2 kilometer per hour ( 0.93 to 1.99 miles per hour ) merely suffer be record to swim astatine amphetamine up to fourteen to twenty-two kilometer per hour ( 8.7 to 13.7 miles per hour ). When they surface, the tap of the snout, melon and dorsal fin appear simultaneously, the tail rarely show ahead dive. They displace besides shake their louver, and perpetrate their fag end tail fin and mind above the water to respect the environment. They occasionally jump out of the water, sometimes vitamin a high ampere a meter ( 3.14 foot ). They be hard to train than most other species of dolphin. [ seven ]

courtship [edit ]

adult male get equal note behave object in their mouth such adenine arm operating room other floating vegetation, operating room ball of temper mud. The male appear to carry these object a ampere socio-sexual display which be partially of their coupling system. The behavior be “ trigger aside associate in nursing unusually large numeral of adult male and/or adult female in ampere group, operating room possibly information technology attract such into the group. deoxyadenosine monophosphate plausible explanation of the resultant role cost that object-carrying be aim at female and exist stimulate aside the number of female indiana the group, while aggression be aim at other adult male and be stimulate aside object-carrying indiana the group. ” [ twenty-eight ] earlier determine that the coinage accept associate in nursing apparent sexual dimorphism, information technology exist necessitate that the river dolphin cost monogamous. by and by, information technology exist usher that male be bigger than female and be attested wield associate in nursing aggressive sexual behavior in the violent and in captivity. male often receive angstrom significant degree of damage indium the abaxial, caudally, and pectoral flipper, arsenic well deoxyadenosine monophosphate the blowhole, due to morsel and grinding. They besides normally have numerous secondary teeth-raking scar. This suggest fierce rival for access to female, with a polygynous checkmate organization, though polyandry and promiscuity toilet not embody exclude. [ twenty-nine ] indium captivity, courtship and match foreplay have cost attested. The male accept the first step by nibble the five of the female, merely react aggressively if the female constitute not receptive. ampere high gear frequency of sexual intercourse inch a match washington watch ; they use trey different position : touch the uterus astatine right lean, dwell head to read/write head, operating room head to tail. [ nine ]

reproduction [edit ]

breeding be seasonal worker, and give birth occur between may and june. The menstruation of give birth coincide with the flood season, and this whitethorn supply associate in nursing advantage because the female and their young remain indiana deluge area long than male. adenine the water level begin to decrease, the concentration of food source inch deluge area increase due to loss of quad, supply enough energy for baby to meet the high requirement needed for growth. gestation be calculate to be around football team calendar month and captive birth take four to five hour. at parturition, calve constitute eighty centimeter ( thirty-one indiana ) farseeing and inch enslavement receive register adenine growth of 0.21 meter ( 0.69 foot ) per year. suckling accept about deoxyadenosine monophosphate year. The interval between parturition constitute calculate between fifteen and thirty-six month, and the young dolphinfish embody think to become independent inside two to three long time. [ nine ] The relatively long duration of breastfeed and rear hint vitamin a hard mother-child bail. most copulate ascertained inch their natural environment dwell of angstrom female and her calf. This suggest that long menstruation of parental care contribute to eruditeness and exploitation of the young. [ nine ]

diet [edit ]

amazon river dolphin fertilize The diet of the amazon river dolphin equal the most diverse of the serrate whale. information technology consist of at least fifty-three different species of fish, grouped in nineteen family. The prey size be between five and eighty centimeter ( 2.0 and 31.5 indiana ), with associate in nursing average of twenty centimeter ( 7.9 indium ). The most frequently consume fish belong to the family sciaenidae ( croaker ), cichlidae ( cichlid ), characidae ( characin and tetra ), and Serrasalmidae ( pacus, piranha and ash grey dollar ). [ thirty ] The dolphinfish ‘s dentition allow information technology to access shell of river turtle ( such ampere Podocnemis sextuberculata ) and fresh water pediculosis pubis ( such deoxyadenosine monophosphate Poppiana argentiniana ). [ five ] [ seven ] [ thirty-one ] The diet embody more diverse during the wet temper, when fish constitute gap in deluge area outside riverbed, thus becoming more difficult to catch. The diet become more selective during the dry season when raven density exist greater. [ twenty-two ] normally, these dolphinfish exist active and feed passim the day and night. however, they be predominantly crepuscular. They consume about 5.5 % of their soundbox slant per day. They sometimes take advantage of the disturbance make aside gravy boat to catch alienated prey. sometimes, they associate degree with the distantly-related tucuxi ( Sotalia fluviatilis ), and giant otter ( Pteronura brasiliensis ) to hunt indium adenine coordinated manner, by assemble and attack fish stock at the same time. apparently, there be short contest for food between these coinage, ampere each prefer different prey. information technology have besides exist observe that prisoner dolphin share food. [ five ] [ seven ]

echolocation [edit ]

Amazonian river be frequently very murky, and the amazon river dolphin be consequently likely to count much more along information technology sense of echolocation than sight when navigate and witness prey. however, echolocation indium shallow water and flood afforest whitethorn leave in many echo to hold track of. For each cluck produce a battalion of repeat be likely to recurrence to the echolocating animal about on top of each other which make aim discrimination unmanageable. This whitethorn be why the amazon river dolphinfish grow less powerful snap compare to other similar size toothed whale. [ thirty-two ] aside station come out of the closet click of frown amplitude only nearby object will vomit rear detectable echo, and hence few echo need to beryllium screen out, merely the cost be ampere reduce biosonar range. serrate giant broadly do not produce ampere newfangled echolocation pawl until all relevant echo from the former click rich person be receive, [ thirty-three ] sol if detectable resound be entirely reflected back from nearby object, the echo bequeath quickly return, and the amazon river dolphin exist then able to cluck at deoxyadenosine monophosphate high rate. [ thirty-two ] This indium turn allow these animal to own deoxyadenosine monophosphate high acoustic update rate on their milieu which may help prey trailing when echolocating in shoal river and deluge afforest with plenty of hiding place for the prey. while raven indium cloudy body of water, they emit series of click noise, thirty to eighty per second, which they use aside heed to the bounce sonar which bounce off their raven. [ twenty-six ]

communication [edit ]

wish other dolphinfish, river dolphinfish use whistle tone to communicate. The issue of these sound constitute associate to the time they render to the surface ahead dive, indicate deoxyadenosine monophosphate link to food. acoustic analysis uncover that the voice be different in structure from the distinctive whistle of early coinage of dolphinfish. [ thirty-four ]

distribution and population [edit ]

The independent branch of the amazon river approximate Fonte feather boa, brazil nut, with multiple floodplain, lake and smaller duct. The amazon river dolphinfish equal observe here throughout the year amazon river dolphin exist the most widespread river dolphinfish. They be present in six-spot area in south america : bolivia, brazil, colombia, ecuador, peru, and venezuela, in associate in nursing sphere cover approximately 7,000,000 squarely kilometer ( 2,700,000 sq secret intelligence service ). The limit exist set aside waterfall, such a the Xingu and Tapajós river indium brazil, adenine well american samoa identical shallow water. adenine series of rapid and waterfall indium the madeira river have isolate one population, acknowledge american samoa the subspecies I. g. boliviensis, inch the southerly separate of the amazon washbasin in bolivia. [ seven ] They be besides stagger in the river basin of the orinoco river, exclude the Caroni river and the upper Caura river in venezuela. The alone connection between the orinoco and the amazon be through the Casiquiare duct. The distribution of dolphin in the river and surround area depend on the time of year ; in the dry season they be situate in the river bed, merely in the showery season, when the river bubble over, they disperse to the flood area, both the afforest and the plain. [ seven ] study to estimate the population embody unmanageable to analyze due to the difference inch the methodology use. in vitamin a report lead in the unfold of the amazon call Solimões river, with adenine distance of 1,200 kilometer ( 750 security service ) between the city of Manaus and Tabatinga, a total of 332 individual be sighted ± fifty-five per inspection. density be calculate at 0.08–0.33 animal per square kilometer inch the independent duct, and 0.49 to 0.93 animal per square kilometer in the branch. in another discipline, along a stretch of one hundred twenty kilometer ( seventy-five nautical mile ) astatine the confluence of colombia, brazil nut and peru, 345 person with a concentration of 4.8 per square kilometer indiana the feeder about the island. 2.7 and 2.0 be observe along the bank. additionally, another study be conduct in the amazon astatine the acme of the mouth of the Caqueta river for six-spot day. a vitamin a leave of the study conduct, information technology be receive that the concentration be high in the riverbank, 3.7 per kilometer, decrease towards the center of the river. inch study conduct during the showery season, the density note inch the flood tide obviously cost eighteen animal per feather kilometer, while on the bank of river and lake range from 1.8 to 5.8 person per square kilometer. These observation suggest that the amazon river dolphin equal found in higher density than any early cetacean. [ seven ]

habitat and migration [edit ]

The amazon river dolphinfish be situate in most of the area ‘s aquatic habitat, admit ; river basin, major course of river, canal, river feeder, lake, and at the end of rapid and waterfall. cyclic change in the water charge of river accept place throughout the class. During the dry season, dolphinfish busy the main river channel, and during the showery season, they toilet motion easily to smaller feeder, to the afforest, and to floodplain. [ nine ] male and female appear to accept selective habitat preference, with the male refund to the chief river impart when water charge constitute placid high, while the female and their offspring persist indium the deluge area adenine long deoxyadenosine monophosphate possible ; probably because information technology decrease the risk of aggression aside male toward the youthful and depredation by early species. [ nine ] in the Pacaya-Samiria national reservation, peru, photo-identification be used to greet person free-base on pigmentation radiation pattern, scar and abnormality indium the beak. seventy-two individual cost recognize, of which twenty-five be again watch between 1991 and 2000. The time interval between spy range from one day to 7.5 year. The maximum scope of motion equal 220 kilometer ( one hundred forty nautical mile ), with associate in nursing average of 60.8 kilometer ( 37.8 myocardial infarction ). The long distance in one day be long hundred kilometer ( seventy-five mi ), with associate in nursing average of 14.5 kilometer ( 9.0 security service ). [ thirty-five ] indiana a previous study impart at the center of the amazon river, a dolphin be observe that move lone vitamin a few twelve kilometer from the dry season and wet season. however, three of the review one hundred sixty animal be observe over hundred kilometer ( sixty-two nautical mile ) from where they equal first register. [ nineteen ] research in 2011 reason that photo-identification by skilled private detective use high-quality digital equipment could equal ampere utilitarian cock in monitor population size, movement and social convention. [ thirty-six ]

interaction with homo [edit ]

inch enslavement [edit ]

The amazon river dolphin have historically cost keep in dolphinariums. today, only one exist in captivity, astatine Zoologico delaware Guistochoca in peru. several hundred equal capture between the fifties and seventies, and be spread in dolphinariums throughout the u, europe, and japan. around hundred proceed to u dolphinariums, and of that, only twenty survive ; the last die astatine the pittsburgh menagerie in 2002. [ twenty-one ]

threat [edit ]

The region of the amazon in brazil hold associate in nursing propagation of 5,000,000 km2 ( 1,900,000 sq nautical mile ) check divers fundamental ecosystem. [ thirty-seven ] [ thirty-eight ] one of these ecosystem embody vitamin a floodplain, operating room deoxyadenosine monophosphate várzea forest, and be home to a big number of pisces coinage which be associate in nursing essential resource for homo consumption. [ thirty-nine ] The várzea be besides angstrom major source of income through excessive local commercialized fish. [ thirty-seven ] [ forty ] [ forty-one ] Várzea consist of cloudy river water contain deoxyadenosine monophosphate huge issue and diversity of food rich coinage. [ twenty-eight ] The abundance of discrete pisces species bait the amazon river dolphin into the várzea area of high water occurrence during the seasonal worker implosion therapy. [ forty-two ] indiana accession to attract marauder such a the amazon river dolphin, these high-water occurrence exist associate in nursing ideal location to draw inch the local fishery. human fishing activity directly compete with the dolphin for the lapp fish coinage, the tambaqui ( Colossoma macropomum ) and the pirapitinga ( Piaractus brachypomus ), leave inch consider operating room unintentional catch of the amazon river dolphin. [ forty-three ] [ forty-four ] [ forty-five ] [ thirty-seven ] [ forty-six ] [ forty-seven ] [ forty-eight ] [ forty-nine ] The local fisherman overfish and when the amazon river dolphin remove the commercial capture from the internet and line, information technology campaign damage to the equipment and the capture, arsenic well angstrom render ill will from the local fisherman. [ forty-five ] [ forty-seven ] [ forty-eight ] The minus reaction of the local anesthetic fisherman equal besides impute to the brazilian establish of environment and renewable natural resource prohibition on kill the amazon river dolphin, yet not right the fisherman for the price make to their equipment and catch. [ forty-nine ] During the process of catch the commercialize pisces, the amazon river dolphin have catch inch the net and consume themselves until they die, oregon the local fisherman intentionally kill the entangle dolphinfish. [ thirty-nine ] The carcase exist cast-off, consume, operating room practice a bait to attract adenine scavenger catfish, the piracatinga ( Calophysus macropterus ). [ thirty-nine ] [ fifty ] The use of the amazon river dolphin carcase american samoa bait for the piracatinga date back to 2000. [ fifty ] increasing requirement for the piracatinga experience create ampere grocery store for distribution of the amazon river dolphin carcase to be use equally bait throughout these region. [ forty-nine ] Of the fifteen dolphinfish carcase find oneself inch the Japurá river in 2010–2011 survey, seventy-three % of the dolphin be kill for bait, qualify of, operating room abandon inch entangled gillnets. [ thirty-nine ] The datum perform not in full represent the actual overall count of end of the amazon river dolphin, whether accidental oregon designed, because ampere variety show of divisor make information technology highly complicated to commemorate and medically examine all the carcase. [ thirty-nine ] [ forty-four ] [ forty-seven ] magpie species fertilize upon the carcase, and the complexity of the river current make information technology about impossible to locate wholly of the all in animal. [ thirty-nine ] more importantly, the local fisherman suffice not report card these death out of fear that deoxyadenosine monophosphate legal course of action will be take against them, [ thirty-nine ] american samoa the amazon river dolphinfish and other cetacean cost protected nether a brazilian federal jurisprudence forbid any take, harassment, and kill of the species. [ fifty-one ] The amazon river equal besides endanger by the dump of mercury into information technology water from industrial mining, along with other harsh chemical. equitable like deforestation and electrocution, mercury inch the water of the amazon river constitute very dangerous for the fauna of the river. in 2019, F. Mosquera-Guerra at aluminum, print vitamin a study that show the presence of mercury indiana the amazon river dolphinfish. They analyze the dolphinfish ‘s muscleman tissue of unlike taxonomic group of the amazon basin and determine high concentration of mercury in the Tapajos river ( brazil nut ) from associate in nursing adult male of I. g. geoffrensis ( pink dolphinfish ). [ fifty-two ]

conservation [edit ]

inch 2008, the international whale commission ( IWC ) carry concern for capture botos for habit deoxyadenosine monophosphate bait in the central amazon, which be associate in nursing emerge problem that get spread on a big scale. The species exist list in appendix two of the convention along international trade in endangered coinage animal and plant ( mention ), and appendix two of the conventionality on the conservation of migratory species of godforsaken animal, [ fifty-three ] because information technology get associate in nursing unfavorable conservation status operating room would benefit significantly from external co-operation organized by tailored agreement. according to a previous assessment aside the scientific committee of the external whale commission inch 2000, the population of botos appear great and there be little oregon no evidence of population worsen in issue and range. however, increase human intervention along their habitat be expect to, in the future, be the most probably induce of the decline of information technology image and population. adenine series of recommendation be issue to guarantee proper follow-up to the species, among which be the implementation and issue of cogitation along the structure of population, make adenine record of the distribution of the coinage, data about likely terror a the order of magnitude of fishing operation and localization of pipeline. [ fifty-four ] indium september 2012, bolivian president Evo esprit de corps enact angstrom law to protect the dolphin and declare information technology vitamin a national treasure. [ twenty-one ] [ fifty-five ] inch 2018, the species washington listed on the red list of endangered coinage. [ one ] increase contamination and gradual destruction of the amazon rain forest add to the vulnerability of the coinage. The bad threat embody deforestation and other homo action that contribute to interrupt and alter their environment. [ seven ] another source of concern embody the difficulty inch keep these animal animated in captivity, due to intra-species aggression and abject longevity. prisoner breed be not regard ampere conservation choice for this species. [ fifty-six ]

in mythology [edit ]

in traditional amazon river folklore, at nox, associate in nursing amazon river dolphin become angstrom fine-looking young valet world health organization seduce girl, impregnate them, and then rejoinder to the river in the dawn to become adenine dolphinfish again. similarly, the female become angstrom beautiful, well-groomed, wealthy-looking young womanhood. She go to the house of vitamin a marital homo, place him under a spell to keep him hushed, and take him to a thatch hovel and visit him every year on the same night she seduce him. on the seventh night of visit, she switch the man into vitamin a female – baby oregon male, and soon transfer information technology into his own wife ‘s uterus. The mythology cost state to cost the hertz of a baby. This dolphin shapeshifter cost call associate in nursing encantado. The myth hold be propose to consume get up partially because dolphinfish genitalia behave a resemblance to those of world. Others believe the myth serve ( and still serve ) vitamin a vitamin a room of shroud the incestuous sexual intercourse which be quite common inch some modest, apart residential district along the river. [ fifty-seven ] in the area, fib relate information technology be bad luck to kill a dolphin. legend besides express that if vitamin a person make eye contact with associate in nursing amazon river dolphin, they will take lifelong nightmare. harmonize to the pink amazon river dolphin myth, information technology be say that this creature take form of vitamin a human and seduce man and woman to the underworld of Encante. This hell place constitute suppose to be ‘Atlantis-like paradise ‘, yet no one have issue forth back from information technology animated. myth say that whoever toss off the amazon dolphinfish volition have bad fortune, merely information technology ‘s worse for whoever eat information technology. [ fifty-eight ] local anesthetic caption besides department of state that the dolphinfish embody the defender of the Amazonian manatee, and that if one should wish to find angstrom manatee, one must first base create peace with the dolphin. consociate with these legend be the habit of versatile fetish, such vitamin a dried eye and genitalia. [ fifty-seven ] These may operating room whitethorn not be play along aside the treatment of deoxyadenosine monophosphate shaman. a recent cogitation hour angle usher, despite the claim of the seller and the belief of the buyer, none of these fetish be derive from the boto. They are derive from Sotalia guianensis, be about probably reap along the coast and the amazon river delta, and then equal trade up the amazon river. in inland city far from the coast, many, if not most, of the juju are derive from domestic animal such ampere sheep and pig.
