These creatures have became fox sized predators, they will hunt after their own ancestors, the Lepus duilleog. They have evolved alot of strange traits, such as circular spiracles, 2 small useless legs, and claws.
also, it may seem strange that they can get so large yet have no skeleton, but Boston dynamics have created robots as large as humans, and robots usually kind of have an exoskeleton so if they can do it these could maybe do it
