Always seeking new accommodation

The common hermit crab lives in an empty seashell. This enables it to protect its soft and vulnerable abdomen. It does not form its own shell. When it outgrows its seashell, it must seek a new one. The common hermit crab inspects its new home thoroughly before moving in.

The perfect fit

The common hermit crab's tail fits perfectly into a seashell. Its abdomen is spirally curved and its back legs enable it to clasp onto the seashell. If the common hermit crab is frightened, it retracts completely into the seashell and blocks the entrance using its large claws.

Win-win situation

The common hermit crab lives alongside polyps, sponges and sea anemones that attach themselves to the seashell. This provides the common hermit crab with good camouflage at the sea bottom. These animals also benefit from the fragments of food discarded by the common hermit crab.

The common hermit crab in Denmark

You can experience the common hermit crab at depths of 10-30 meters, but you can also see it in slightly shallower water near the coast.
