The Erythrinidae are a family of fishes found in rivers and other freshwater habitats from Costa Rica south as far as Argentina.

They are common and are caught with hooks by fishermen, partially because of their voracious behaviour.

They are sometimes called trahiras (also spelled trairas) or tarariras.

Some species can breathe air, enabling them to survive in water low in oxygen,[1] and even to move over land between ponds.

The 16 species are contained in extant (living) genera,[2] plus another extinct species in a separate genus:[3] Media related to Erythrinidae at Wikimedia Commons Data related to Erythrinidae at Wikispecies
