Book Title: The animal life of our seashore.
Caption: Fiddler (Gelasimus vocator)
Educational Notes: Dont be fooled: while a Fiddler crab may look like its playing a fine tune, theyre actually just eating! Male Fiddler crabs have large front claws, and rather than fiddling, the up and down movement of their small front claw over their larger claw is likely them enjoying a delicious meal of algae, mollusks, worms, or other underwater entrée. Their enlarged claw isnt just used for eating though. Males in some crab species wave their big claws to attract females, who, by the way, dont have enlarged front claws like their male counterparts. There are many kinds of Fiddler crabs living in different environments all over the world. They come in different sizes, shapes, and colors too. Similar to kids getting rid of clothes that no longer fit, crabs shed their shells as they grow. And, if they lose a leg or a claw, they simply grow another one. This is a good thing for the males because male fiddler crabs have been known to lose a claw when combating a rival fiddler crab.
