    Hydrurga – Leopard seal

    The ends of the mouth are permanently curled upwards that look like a smile or a menacing grin

    Leopard seals have slender and long bodies with dark grey on their back and silvery grey on the underside. There are light and dark spots on the whole body that resemble the coat of a leopard. They have a loose jaw that can open up to 160o with sharp front teeth and locked molars, allowing them to strain krill from the water.

    Antarctic krill make up around 45% of their diet, but they also prey on Weddell seals, crabeater seals, Antarctic fur seals, penguins, cephalopods, and fish. They are often quiet on the ice, but when they are in the water, they make growling noises, trills, low-frequency moans, and grunts.
