The alligator snapping turtle is the largest freshwater turtle in the world. It lies practically motionless on the bottom of a lake or river. A thick layer of algae grows on its shell to help it blend in with its habitat. Opening its mouth, it wiggles a pink worm-like tongue to lure in passing fish and—SNAP!—dinner is served.
Turtles are very long-lived animals, and alligator snapping turtles can live to be 100 years old.
