Crabs are not reptiles, crabs are in the Arthropoda Phylum.
The question might presume a fact not in evidence: fiddler crabs are not chordates (phylum chordata, with internal skeletons) but instead are phylum arthropoda, characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.
Fiddler crabs belong in various groups (taxa) in their biological classification: kingdom Metazoa; phylum Arthropoda; subphylum Crustacea; class Malacostraca; order Decapoda; infraorder Brachyura; family Ocypodidae; genus Uca. About a hundred species of fiddlers have been described.
Oh, dude, fiddler crabs are like the hipsters of the crab world. They're all about that organic, gluten-free diet, munching on algae, detritus, and tiny organisms they find in the sand. So, yeah, they're basically the health nuts of the beach, living their best life one tiny snack at a time.
