The smooth-coated otter is a large predator from the mustelid family that swims excellently and lives near freshwater bodies in South and Southeast Asia. It has short smooth fur that hardly gets wet, and a strong tail that helps it move quickly in the water.
The smooth-coated otter differs by its very smooth fur, which repels water better than that of other otters, and often lives in small groups. It is important for nature because it regulates fish populations and maintains the health of water bodies.
