WHAT IS A BARNACLE?Barnacles are small animals, which "glue"

themselves to rocks, piers, ships, and even turtles and whales. Inside its hard shell, the

barnacle has a soft, shrimp-like body. At feeding time, the animal opens its shell at the

top, sticks out three pairs of feathery legs, and waves them back and forth to capture

small food particles.
