The tailwalker split off from luceremundare serpentes reptum limus. It has evolved primitive lungs, much like Earth's lungfish, and comes out to the shore to eat anything it can. They are opportunist omnivores, who will eat worms, baby plents, plants, and anything else they can. Their teeth now have front meat-eating teeth and back grinding teeth, as well as a beak to gnaw though hard plant fibers and bone. They also sun themselves on the shore. They still have the camouflage like the rest of their relatives, so they can blend in with the teflonpalms by turning blue, turn purple to blend in with the purple plants, turn green to blend in with plents, or even turn black to absorb more heat to warm up their cold blood. They reproduce via sexual reproduction and lay their sticky eggs in bubbleweed plants as well as other aquatic plants.
