Lizardworm

The Lizardworm branched off from the Leatherback Scuttlecrab after the Scuttlecrab colonized the Irinya Islands. It feeds on its ancestral Scuttlecrabs using its newly formed jaw. This feature is the result of the insectoid mandibles of the Scuttlecrab fusing together and beginning to move up and down rather than together and apart. The pincers of the Scuttlecrab became down turned and specialized for walking, while its first rear legs moved further towards the rear. The body lengthened and became more worm-like. Its second rear legs degenerated and became a pair of small spines halfway down and on each side of its tail. At some stage during its evolution, the Lizardworm lost its symbiotic relationship with Testudohexapodia 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 5,000-10,000 years apart.
