Hermit crab: A hermit crab is a type of crab that belongs to the family Paguridae. Unlike most other types of crabs, hermit crabs do not have a hard shell of their own, so they must use the empty shells of other marine creatures, such as snails or bivalves, to protect their soft abdomens.
Hermit crabs are found in oceans all around the world, as well as in freshwater and on land. They are typically small in size, with most species ranging from just a few millimeters to a few centimeters in length.
In addition to using shells for protection, hermit crabs are known for their ability to scavenge for food and their unique behaviors, such as carrying sea anemones on their shells for defense and using their claws to wave and communicate with one another. Hermit crabs also undergo a process called molting, where they shed their exoskeletons to grow larger ones, leaving them vulnerable to predators until their new shell hardens.
