Category Sci/Tech | Friday, July 23rd, 2010
Snakeheads (Channidae) are a family of freshwater fish native to Africa and Asia. These predatory fish are distinguished by a long dorsal fin, large mouth and shiny teeth. They have a physiological need to breathe atmospheric air, which they do with a suprabranchial organ: a primitive form of a labyrinth organ. There are two extant genera, Channa in Asia, and Parachanna in Africa, consisting of 30-35 species.
