The Great Hermit Crab Shell Swap
by twistedsifter
When a big, new shell washes ashore, hermit crabs congregate and position themselves from largest to smallest in a vacancy chain where everyone tries to upgrade to a bigger home. An excerpt from BBC’s Life Story Series (episode ‘Home’) and narrated by David Attenborough.
