Oriental small-clawed otters (Aonyx cinerea) resting after swimming. This otter, also known as the Asian small-clawed otter, is the smallest otter species in the world. It is found in parts of Indonesia, Malaysia and the Philippines, as well as in southern India and China. Its name refers to its tiny claws, which do not protrude beyond the ends of its finger pads. This gives its paws increased sensitivity, allowing them to feel under mud and rocks to locate the mussels, snails and crustaceans they eat.
