View Parent Category Labyrinth Fishes

These unique fishes have a labyrinth organ, a structure in the fish's head which allows them to "breathe" atmospheric oxygen. Fish of this family are commonly seen gulping at air at the surface of the water; which then passes out of their gills or mouth when they dive beneath the surface. Bettas, gouramis and snakeheads would belong to this family.
