hermit crab shell

Adopted spiral home

The shell a hermit crab inhabits—borrowed from a dead snail or other mollusk, since hermit crabs don't grow their own.

As the crab grows, it must find progressively larger shells.

The term extends figuratively to any borrowed or temporary dwelling: She moved from apartment to apartment, each one just another hermit crab shell.
