A male fiddler crab's oversized claw not only looks cool to the ladies, but new research suggests it literally helps crabs to stay cool. Researchers placed crabs under a hot light and took their temperatures. They found that the temperatures of crabs missing their large claw rose faster and reached a higher maximum than intact crabs.
