Leatherback Scuttlecrab

The Leatherback Scuttlecrab evolved from a line of the Crawling Stumpworm that had formed a symbiotic relationship with Textudohexapodia Spherus. T. Spherus benefits from this relationship as it can distribute it's spores to a much larger area and it can also bloom constantly due to the supply of nutrients it gains from it's host. The Scuttlecrab benefits as it gains a small amount of energy through photosynthesis and the T. Spherus cells also secrete a substance which both neutralises the acid of the Stumpworm Sucker and prevents the Stickyballs from attaching themselves.

The front legs on each side have fused into a pair of pinsers while the four rear legs have become strong enough to lift the scuttlecrab's weight. As a result the Leatherback Scuttlecrab is a fast and efficient small predator, it can hunt small plents, such as young nobomaton and even kills Stumpworms and other Scuttlecrabs.Another development of the Leatherback Scuttlecrab is a thick leatherlike skin which has grown over it's exoskelleton. This hide is made from a combination of modified internal flesh cells and of the symbiotic Textudohexapodia Spherus cells. The Scuttlecrab lives predominantly on the beaches although it's range extends a short way into the flatlands.
