One of the smaller crocodilian species, reaching around 2 m (reports of 3 m individuals exist in Chinese historical literature, but this is unlikely today). Adults may weigh up to 40kg. Juveniles are black with bright yellow cross-banding, similar to juveniles of A. mississippiensis, which have a greater number of bands. Unlike A. mississippiensis, however, A. sinensis has bony plates on each upper eyelid (palpebrals). The end of the snout is slightly upturned, and is more tapered than A. mississippiensis. The teeth are better adapted for crushing, as they feed extensively on hard-shelled molluscs. The ventral body scales are ossified, making the skin fairly worthless on the international market.
