This large species is similar to the American crocodile. The body is made up of scales (scutes) that vary in shape and strength. Orinoco crocodiles can be identified by the arrangement of dorsal (back) armour with six prominent scales on the back of the neck. Osteoderms (bony deposits within each scale) are rough in texture and are often different in colour. Orinoco crocodiles have no osteoderms on their light coloured belly, Another identifying feature of the Orinoco crocodile is the narrow snout which slopes upward near the tip. The nostrils are set at the end to allow breathing while mostly submerged. The tongue is wide and attached to the bottom of the mouth and does not aid in the capturing of prey. Their body colour varies from grey-green, tan to grey scattered with dark green. The legs are short and strong; the long tail is quite powerful.
