Those of you who guessed it was a male Fiddler Crab (Gelasimus sp.), you’re correct! Only males have an enlarged claw, whereas females have two equal-sized small ones.

The male Fiddler Crab favours different “hands” for different purposes. The larger claw is used for courtship and fighting, while the smaller claw has a spoon shaped tip that is used for feeding!
