Its paws are a distinctive feature, its claws not extending beyond the fleshy end pads of its partially webbed fingers and toes. This gives it a high degree of manual dexterity so that it can use its paws to feed on molluscs, crabs and other small aquatic animals.

The sides of the neck and head are brown, but its cheeks, upper lip, chin, throat and sides of the neck are whitish. The Oriental small-clawed otter or Aonyx cinereus skull is short.
