Lizardworm

The Lizardworm branched off from the Leatherback Scuttlecrab after the Scuttlecrab colonised the Irinya Islands. It feeds on it's ancestral Scuttlecrabs using it's newly formed jaw. This feature is the result of the insectoid mandibles of the Scuttlecrab fusing together and begining to move up and down rather than together and apart. The pinsers of the Scuttlecrab became downturned and specialised for walking while it's first rear legs moved further toward the rear. The body lengthened and became more wormlike. It's second rear legs degenerated and became a pair of small spines half-way down and on each side of it's its tail. At some stage during it's evolution, the Lizardworm lost it's symbiotic relationship with Textudohexapodia Spherus. The Lizardworm is native to the Irinya Islands.

Although the Swampgrass and the Lizardworm are both part of the same generation, they actually arose 5000-10,000 years apart.
