Animal field guide

Hermit Crab

Paguroidea

The Hermit Crab teaches Fit through a soft body protected by a borrowed shell that must change as growth continues. Its shell searching, shore movement, vulnerable abdomen, and housing swaps show that protection can become a prison when it stops fitting. Its lesson is to leave the shell that limits the life being built.
