Channidae - Snakeheads

The snakeheads are members of the freshwater perciform fish family Channidae, native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins, large mouths, and shiny teeth. They breathe air with gills, which allows them to migrate short distances over land. They have suprabranchial organs, which are primitive forms of labyrinth organs, that develop when they grow older.

The two extant genera are Channa in Asia and Parachanna in Africa, consisting of more than 50 species.

They are valuable as a food source and have become notorious as an intentionally released invasive species. These fish have been kept as pets, but as they get larger, people let them go into ponds, lakes, and rivers, making these fish invasive.
