What are Hermit Crabs?

Hermit crabs are crustaceans. This means they’re actually related to a lot of the shellfish we eat, like lobsters and shrimp. They’re also related to some creatures we wouldn’t dream of eating, like Pill Bugs and Sand Fleas.

Where do they come from?

Most of the Hermit Crabs sold in petshops and fairs throughout the U.S. come from Florida or various islands in the Caribbean where they can often be found in large groups roaming the beaches for food. Since they are nocturnal, meaning that they are mostly active in the evening, tourists and visitors rarely get a chance to see this unusual sight.

Why are they called "Hermit Crabs"?

Well, they are crabs and like any other type of crab, the Hermit Crab’s front pair of legs end in pincers or chelipeds. The pincers themselves differ from each other in that the right pincer is smaller and is used primarily for eating. The left pincer can be much larger and more powerful-looking, and is used mainly for defense. A Hermit Crab will use both pincers for climbing and, as clumsy as they may seem, Hermit Crabs are actually quite good climbers. Their ability to clamber up and around almost any obstacle is something to seriously consider when planning and decorating their enclosure. A sturdy, snug-fitting cover is a must! Hermit Crabs don’t have shells of their own and live in previously empty snail shells or shells that have been discarded by other creatures or Hermit Crabs, hence the name "Hermit". They spend much of their time searching for new shells to call home and can often be seen trying on several shells before settling on a new one to wear. As the Hermit Crab grows, it sheds its outside or exoskeleton, and after a period of rest during which it feels especially vulnerable, it wanders off in search of another shell that fits. Hermit Crabs shouldn’t be handled soon after they shed, and should be given plenty of privacy until their new exoskeleton hardens and they start looking for a new shell. Speaking of handling, except during the period just mentioned above, Hermit Crabs can be handled and even frequently handled as long as care is taken that they are not dropped. Also, you should never try to pull Hermit Crabs from their shells. They will actually allow themselves to be torn apart rather than be forced out of their home!
