Entomosuchus

The entomosuchus has split from the strongjaw lizardworm, and moved into the  Ovi-Hydro plains, where there is lots of competition. It still had to adapt someway, somehow; so it has evolved to eat the young of all of the other lizardworms in the Ovi-Hydro plains. It slices up its young victims with its brutal jaws, with improved, bifurcated teeth. The ridges on the insectoid jaws become sharper. With this powerful set of jaws, young lizardworms will most want to avoid this monster. It retains the habit of eating vandriswoops for supplementation.

The entomosuchus also retains the posterior clinging legs for sexual excitement during copulation.

Due to the pressure from the entomosuchus eating the young and the competition from the fuzzy lizardworm, the  brutish lizardworm becomes extinct in the Ovi-Hydro Plains.
