Sneaky Snakes

It's hard enough to catch a bite to eat when your prey consists of relatively quick moving land animals. But when you're dealing with tiny, lightning fast fish, what can you do to improve your odds that you'll get a meal? Turn yourself into a tentacled water snake. Scientists at Vanderbilt University used high-speed video to capture images of the snake performing an unusual trick in order to force prey to swim directly into its mouth. The snake will lie motionless, its body in a "J" shape, and wait for prey to swim close. When a fish swims by the curve of the "J", the snake flexes the lower part of its body. The fish senses the movement and turns to swim away from the perceived threat... only to end up directly in the snake's mouth. You can see the slow motion video here.
