The leopard seal has a distinctively long and muscular body shape, when compared to other seals. This species of seal is known for its massive reptilian-like head and jaws that allow it to be one of the top predators in its environment. A notable key feature of leopard seals is its counter-shaded coat. A counter-shaded coat is when the dorsal side of the coat is darker than ventral side. Leopard seals have a silver to dark gray blended coat that makes up its distinctive "leopard" coloration with a spotted pattern, whereas the ventral side of the coat is paler in color—ranging from white to light gray. Females are slightly larger than the males. The overall length of this seal is 2. 4–3. 5 m (7. 9–11. 5 ft) and weight is from 200 to 600 kilograms (440 to 1,320 lb). They are about the same length as the northern walrus, but usually less than half the weight.
