Q:

Can hermit crabs live out of their shells?

A:

Hermit crabs have soft, vulnerable abdomens and need to wear shells to protect themselves. A hermit crab without a shell eventually falls victim to predators or even other hermit crabs.

Hermit crabs grow throughout their lives and wear many different shells at different life stages. Pet hermit crabs should have a variety of shell choices available since they are picky about finding a shell that fits well. Hermit crabs that cannot find a replacement shell readily may try to hide behind a piece of coconut fiber or other debris. Pet crabs prefer shells with round openings and smooth internal surfaces.

  • Q:

    What eats hermit crabs?

    A:

    Hermit crabs use their shells to hide from predators like seagulls, larger crabs, sea stars and snailfish. These animals are at their most vulnerable when they leave one shell for another, which they must do as they grow because their shells do not grow with them. However, some predators can either bite through the hard shell or pull the crab out and eat it.
