The Neotropical otter is a semi-aquatic mammal from the mustelid family. It lives in rivers, lakes, and swamps of Central and South America, has a long tail, and swims excellently.
The Neotropical otter differs from other otters in its long tail and smaller body size. It is important for nature because it regulates fish populations and maintains the health of aquatic ecosystems.
