Trahiras
Erythrinidae
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.
The Erythrinidae include cylindrical fish with blunt heads, and prey on other fish. They can reach lengths up to 90 cm (35 in). Some species can breathe air, enabling them to survive in low oxygen conditions; in Hoplerythrinus unitaeniatus this ability is well studied. Some may even be able to move over land between ponds.
