What is the natural habitat of hermit crabs in the wild?

The natural habitat of hermit crabs in the wild is generally in coastal waters. There are more than 500 species of hermit crabs worldwide. Some hermit crabs go to deeper waters but most reside near the coast for better food sources.

The lifespan of a hermit crab is up to 10 years. They generally weigh up to 18 ounces. Hermit crabs have an omnivore diet that includes plankton, invertebrates and small fish.

The hermit crab wears its protection on its back to protect its soft under-body. The protection is in the form of a shell that previously belonged to another animal. As the hermit crab grows, it moves to larger shells.
