The hermit crab is a type of crab that doesn't have a very hard shell. As the hermit crab grows in size, it must find a larger shell. Most hermit crab species live on the ocean floor, but many live on land.
Hermit crabs are invertebrates, animals without a backbone.
They have an exoskeleton, an outer shell that provides support for their body but does not provide much protection from predators. They vary widely in color, from red to brown to purple, with stripes, dots, and other patterns. They eat worms, plankton , and organic debris.
