Found commonly along the African coast, a species of Sesarmid crab feeds on fallen leaves, and is especially sensitive to vibrations. They can detect a leaf falling on the mud while hidden within their burrows. These mangrove leaf crabs can sometimes be seen scurrying out to grab a newly fallen leaf within seconds of it hitting the ground, and then rushing back to their burrows with their nutritious prize. Indeed, great battles often ensue as these crabs fight each other for a scarce morsel. These crabs are easily recognized by their large size, and their equal-sized orange-red claws.
