A LIMPET is a type of rock-clinging mollusc, which is a soft-bodied invertebrate animal. It has a conical shell and a muscular foot that it uses to attach itself to rocks and other hard surfaces in the ocean. Limpets are found in many parts of the world, including the Atlantic, Pacific, and Indian Oceans. They feed on algae and other small organisms, and are an important part of the marine food chain.
