A. cinereus
The Eastern Clawless Otter is the smallest otter in the world. It has very short claws on its paws, sensitive skin on the fingers, and thick fur that helps it live near rivers, lakes, and swamps in Southeast Asia.
The Eastern Clawless Otter differs from other otters by its very short claws and ability to use paws like hands to search for food. It is important for nature because it controls the population of crustaceans and helps keep water bodies clean.
