Do snakeheads "walk?"
Although claims of their mobility have been greatly exaggerated, several species of snakeheads are able to wriggle overland from one body of water to another, particularly if the ground is wet. They do this by flexing their body and pushing with their tail, while using their broad pectoral fins to stabilize their head. It is unknown how far they can travel on land. This crawling ability is reduced in larger species of snakeheads as they reach adulthood. The introduced blotched snakehead in Madagascar is known to crawl onshore, allow its body to be covered with ants, and then return to the water where the ants are dislodged and subsequently eaten by the fish. Still, survival outside the water is limited for snakehead. Although they do breathe air by gulping at the water’s surface, they are fish, and like any fish, they require water to be able to live.
