Tentacled Snake
(Cheryl Carlin)
Name: The tentacled snake, Erpeton tentaculatus, of Southeast Asia.
Hunts: In the J position.
Exploits: The C-start.
Eats: With very little effort, says Kenneth Catania of Vanderbilt University. When fish perceive a threat, they reflexively turn away and their bodies form a C, known as a C-start. The J position is the stance a hungry E. tentaculatus assumes (1) with its head at the lower end of the J. If a fish swims by, the snake flexes its body (2) scaring the fish into forming a C and landing it in the snake's mouth (3). It's a rare case of a predator exploiting its prey's best defense.
