These Hermit Crabs Line up from Biggest to Smallest. You Won’t Believe What Happens Next.

Filmed on a small Caribbean island off the coast of Belize, a hermit crab which requires a larger, more suitable home for its size waits by an empty oversized shell. Due to a limited supply of abandoned shells in the area more crabs soon show up and a “housing chain” is formed — they size each other up and line up from biggest to smallest. Watch as these house-hunting crabs spring into action as soon as the largest crab vacates its old home and occupies a larger shell.
