A compact marine curiosity with an unexpectedly sculptural appearance, the Bicornis Box Crab (Clappa bicornis) is characterized by its strongly textured, domed carapace and impressive folded claws. The irregular nodules and warm orange-brown coloration give the specimen a rugged, almost stone-like surface.

Originating from Indonesia, this natural crab specimen preserves the distinctive morphology of the species, particularly the broad claws that fold closely against the front of the body, a characteristic feature of box crabs.
