Predatory, voracious eaters of native flora and fauna. Snakeheads can eat other fish that are up to 33% of their size.
The scaled head of the fish resembles that of a snake. These fish can tolerate freezing temperatures, surviving under ice. They can also survive on land, living up to four days without water. They have been heard making grunting noises, similar to the snort of a pig. They originally were brought to Arkansas for the restaurant trade and escaped captivity.
