Mechacrabs were ironically given their name after a sarcastic explorer discovered the species in an underground cave on a spiritual voyage deep in the far east. Mechacrabs have detachable legs and hard, modular shells that they can reconfigure and reattach new legs and hand-made appendages anywhere they need them. It is believed they are incredibly smart and inventive, but the species lacks the physiology necessary for speech or language functions and is plagued by a particularly short natural lifespan.
