Aonyx cinereus (Oriental Small-clawed Otter)

Synonyms: Amblonyx cinereus; Aonyx cinerea

Wikipedia Abstract

The oriental small-clawed otter (Amblonyx cinerea), also known as the Asian small-clawed otter, is the smallest otter species in the world, weighing less than 5 kg. It lives in mangrove swamps and freshwater wetlands of Bangladesh, Burma, India, southern China, Laos, Malaysia, Indonesia, Singapore, the Philippines, Thailand, and Vietnam. 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.
