Check out these creatures’ do-it-yourself approach when it comes to finding a new home for themselves.
These Caribbean hermit crabs use abandoned sea shells as mobile homes and protection from the hot, tropical sun. When the crabs outgrow their shells, they gather together in a line — smallest to largest — and exchange homes. Each crab wiggles out of its current shell and moves right into the next biggest shell in the line.
When Australian weaver ants build their homes, it’s all hands on deck, even if you don’t have any. Strong worker ants link their bodies together to make bridges for other ants to make their way from one leaf to another. What’s interesting is their glue-like spit provides a strong and flexible adhesive to keep their leafy home together. It’s a 10-hour project, but the result is a weatherproof home for the whole gang.
