Hermit Crab Shells I Never Knew Could Fit

#Hermit crabs are decapod crustaceans that belong to the superfamily Paguroidea. There are over #800 species of hermit crabs worldwide, and almost all are ocean dwellers. Hermit crabs have a hard exoskeleton on the front part of their bodies but a soft tail on the other half, which they protect using the discarded #shells of other #animals, like whelks. They’re more closely related to certain kinds of lobsters than to true crabs. Hermit crabs have a curled tail with a hook that enables their bodies to fit inside these borrowed shells. Sometimes when a new shell turns up, hermit #crabs will form a line, biggest to smallest, to see which animal fits the new shell. The next smallest will take that crab’s hand-me-down home, and so on.
