Sheyangs are heavyset reptilians, usually weighing between 80 and 150 kilograms. This gives them a rather ungainly appearance, amplified by their stout limbs and waddle-like walk. Their skin has a thick, amphibious quality and is usually a shade of green or brown, which darkens with age. Sheyangs have no body hair. Their large mouths are full of sharp teeth, giving them a predatory, shark-like appearance. Adults vary between 1.8 and 2.6 meters tall and continue to grow throughout their life span.
