Megajaw

The Megajaw has spilt from its ancestor the Great Megalaukjaw and has evolved towards an apex predator. Its jaw has become super strong in relation to its ancestor's, so much so that the Megajaw can almost bite small prey in two. Along with stronger stomach acid, this has allowed the megajaw to be efficient hunter, which led to the megajaw hunting larger prey. This in turn caused megajaw to grow larger to handle its new prey. With its super powerful jaw, it no longer needed spikes for protection. Now only males have spike on their back as sign of their health. Also hatchlings to nestlings have a full covering of spikes. They have moved to areas with larger plants to hide themselves while hunting. Their sense of smell has improved to help them in their search for prey. The megajaw's top tail finger has grown larger to be used to anchor into the flesh of prey while the other fingers have become small and vestigial.

Their social order has partially dissolved, with megajaws living in mating pairs for life. The two are referred to as a king and queen megajaw. The megajaw being in such a prey rich environment does not have to spend all its time hunting for food. If they are not out roaming the area for food they are resting under the trees saving their energy for when they are hunting. When they find prey, they will position themselves on opposite sides of the prey. One of the megajaws will start chasing the prey and panic it where it will then run into the other megajaw who will either bite or anchor the prey.

The pair will mate every spring to produce 1 to 4 offspring. The eggs will be buried in a protective pile of dirt and debris. When they hatch, they look like immature versions of the adults. It takes 8 years for offspring to mature. New adults will compete with each other for the best mates both male and female. After which, the two will mate for the first time.
