This turtle catches fish by wiggling a built-in, worm-shaped lure on its own tongue
The alligator snapping turtle lies motionless on the riverbed, mouth open, using a thin, pink, worm-like appendage on its tongue that it wiggles to draw curious fish within striking range. Once a fish investigates the 'worm,' the turtle's powerful jaws snap shut in a fraction of a second. Researchers studying the lures across thousands of turtles found the structure, believed to be the only prey-luring body part in any living reptile, varies in color between individuals and populations.
