Male fiddler crabs are lopsided, with one claw that seems about the right size and one very large claw. As you might expect, one function of the larger claw is to attract females.

The sighting, he thought, was very strange. Fiddler crabs weren’t supposed to be north of Cape Cod, let alone Boston. The year was 2012, and a marine heatwave had just occurred.
