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.
