Description

The piraiba is one of the largest catfishes in the world (Pimelodidae) from the large rivers of South America. The species can grow to over three metres and weigh hundreds of kilos, with a greyish, scaleless body, three pairs of long barbels and a broad mouth. Adults live on soft bottoms of deep river channels; juveniles and subadults occur in brackish water of river mouths. As an apex predator it hunts fishes. The stout fin spines can give a painful puncture wound when handled.
