Paiacú or Baiacú is the Brazilian name for the puffer, a fish with a poisonous gland that is very common in the coast of Northeastern Brazil. The name Payaku has remained in the memory of the older Indians and of the group’s leaders, but until the end of the 1980s they were referred to as the cabeludos da Encantada (the long-haired ones from the Encantada Lake) by their non-Indian neighbors.
