The pink dolphin legend of the Amazon

The pink dolphin legend of the Amazon is among Brazil's best-known folk stories. On party nights, the boto leaves the river and turns into a young man dressed in white, with a hat to hide the hole on top of his head, the part of him that never changes.¹ A federal transport department publication tells it the same way: a handsome young man in white clothes and a hat that covers his large nostril, who seduces the young women of the village.⁵

In the story the young man is charming and persuasive. He picks out a woman who is at the dance without company and persuades her to go with him into the river, where, the tale says, he makes her pregnant.² When the day breaks he turns back into a boto and disappears, leaving the woman to return home alone. Versions differ from community to community, but the core is stable: a river lover who comes at night and leaves at dawn.

The legend has a pull that goes beyond romance. The pink dolphin folklore of the Amazon gives the pink dolphin a reputation as an enchanter of women, and the word encantado, enchanted, is a key idea of Amazon river belief.^6,7 A dolphin that rises beside a canoe at dusk and looks at the people in it is easy to imagine as someone else in disguise, which may be why the story has lasted.

The legend sits inside a wider set of beliefs. Interviews with residents of Lake Amanã found that the boto is generally feared, since it is considered to hold supernatural powers.⁸ People described it as an animal that can follow canoes, scare people, enchant them or take them to the encantados, its city under the water.⁷ In that picture the river is not only a place where fish live but a place with another, hidden world.

The same interviews recorded a belief linked to candomblé, in which the spirits of the boto haunt the living by using their bodies, which are called aparelhos.⁹ Some residents also share the widespread Amazonian belief that the animal becomes a white man who seduces girls.¹³ These are not mere curiosities: they show that the dolphin is treated with respect and some caution in many communities, which helps explain the tales that surround it.

A visitor will find that belief and science do not collide on the river. A guide may say the boto is an encantado and then explain, in the same breath, that it is an endangered animal with 28 teeth per half jaw.^14,15 Both statements belong to the same river. Ask your guide which stories their own family tells, because a family version may differ from the printed version, and listening to it is part of the trip.

The boto appears in public life as much as in stories. In the communities of Nova Geração and São Sebastião do Igapó-Açu, at km 260 of highway BR-319, residents are often seen bathing alongside the boto in the late afternoon, according to the transport department that wrote about them.¹¹ The community holds a yearly Festa do Boto Cor-de-Rosa do Igapó Açu around August, with activities on environmental preservation and social responsibility.¹⁰

The department chose the boto-cor-de-rosa as a mascot of that highway, to appear in its social communication and environmental education material.²¹ That is a remarkable fact: an animal that is the star of a legend about seduction is also the face of a campaign on road safety and the environment. Both roles fit together because they both show the boto as something local people know and value.

Treat such scenes with caution. A dolphin that comes close to people who bathe in its river is a different matter from a platform that sells fish portions, where researchers have documented problems for the animals.¹⁷ A resident living beside the dolphins for years is part of the picture; a stream of visitors with food is not.
