Saltwater crocodiles are the largest reptilian species alive today. Adult males can reach up to sizes of 6 to 7 meters. Females are much smaller and do not generally exceed 3 meters, with 2.5 meters considered large. The head is very large and a pair of ridges run from the eyes along the center of the snout. The scales are oval in shape and the scutes are small compared to other species. Young saltwater crocodiles are pale yellow in color with black stripes and spots on the body and tail. This coloration lasts for several years until the crocodile matures into an adult. The color as an adult is much darker, with lighter tan or gray areas. The ventral surface is white or yellow in color. Stripes are present on the lower sides of the body but do not extend onto the belly. The tail is gray with dark bands. Saltwater crocodiles have a heavy set jaw which contains up to 68, and no less than 64, teeth.
