The Amazon River Dolphin, alternately Boto, Boutu, Nay, or Pink River Dolphin [cite web | url = http://www.bbc.co.uk/nature/wildfacts/factfiles/62.shtml | title = Wildfacts: Boto | publisher =
BBC| accessdate = 2007-02-21] ("Inia geoffrensis") is a freshwater river dolphinendemic to the Amazon Riverand Orinoco Riversystems. The largest of the river dolphins, this species is not to be confused with the Tucuxi("Sotalia fluviatilis"), whose range overlaps that of the Amazon River Dolphin but is not a true river dolphin.
IUCNlists various other names to describe this species including Amazon Dolphin, Boto Vermelho, Boto Cor-de-Rosa, Bouto, Bufeo, Dauphin de l'Amazone, Inia, Pink Dolphin, Wee Quacker, Pink Freshwater Dolphin, Pink Porpoise, and Tonina.
The first type specimen was described by
Henri Marie Ducrotay de Blainvillein 1817.
1998 classification lists a single species, "I. geoffrensis", in the genus "Inia", with three recognised subspecies:
*"I.g. geoffrensis" - Amazon basin population (excluding
Madeira riverdrainage area, above the Teotonio Rapids in Bolivia)
*"I.g. boliviensis" - Amazon basin population in the Madeira drainage area
*"I.g. humboldtiana" - Orinoco basin population
Some older classifications listed the "boliviensis" population as a separate species.
In a traditional
Amazon Rivermyth, at night an Amazon River Dolphin becomes a handsome young man who seduces girls, [ [http://www.ancientspiral.com/dolphin1.htm "Whales and Dolphins"] at [http://www.ancientspiral.com ancientspiral.com] ] impregnates them, then returns to the river in the morning to become an Amazon River Dolphin again. This dolphin shapeshifter is called an encantado. It has been suggested that the myth arose partly because dolphin genitalia bear a resemblance to that of humans. In the local area, there are also tales that it is bad luck to kill an Amazon River Dolphin.Legend also states that if a person makes eye contact with an Amazon River Dolphin, that person will have nightmares for the rest of his or her life.
The 1987 Brazilian film [http://pt.wikipedia.org/wiki/Ele,_o_Boto Ele, o Boto] is a supernatural romance featuring an Amazon River Dolphin who has a son by a young woman.
Food and diet
The Amazon River Dolphin has 25-30 peg-like front teeth for catching prey and it mainly eats crustaceans, crabs, turtles, and catfish and also they eat bits of human flesh so beware if ever swimming with them.
