A surge of its enormous body, and it will lunge out of the water, taking its prey in its jaws, either killing it with a massive bite or dragging it down below the surface to drown. An ambush predator, Piranhadon tends to lie in wait near the river banks, using its sensitive barbels to detect the approach of potential prey, as its eyes are poor and can only see differences between light and dark. Already five feet long at birth, a juvenile Piranhadon is already a dangerous aquatic predator, and will devour water birds, fish, amphibians, small dinosaurs, and just about anything else it can catch, including larger terrestrial animals. Young are born live in groups of around a dozen. Male Piranhadon are much smaller than the females and must compete to prove their worth as mates.
