Barnacles: Hated Squatters of the Sea

A barnacle is an animal that lives in the sea. Many people don't think of a barnacle as an animal. That's because they never see it. The animal is hidden inside a shell.
A barnacle has a round body. It also has six pairs of legs. That's twelve legs! But it doesn't use its legs for walking. It uses them to eat with.
Barnacles actually live upside down! Their heads are at the bottom and their legs are sticking up into the water.
