A hermit crab is a crustacean that borrows shells from other animals to protect its soft exoskeleton. Unlike true crabs, a hermit crab's shell is not permanently attached to its body. Hermit crabs live on land and in water, using their front legs for walking and finding food while their back legs help hold them inside their shell. They come in a variety of sizes, with coconut crabs growing quite large, and will change shells as they grow.
