Rals, also known as stone rays, were a species of cold-blooded reptavian native to Bothawui. They had two arms and two legs, each with three digits. Their elongated third fingers were connected to their body by leathery flaps of skin, which formed wings. The remaining digits were tipped with sharp claws. Their small mouths were filled with needle-like teeth and a razor-like beak. Tooth and claw was not their primary method of attack, however: their tails were tipped by a venomous stinger.
