The cat otter, or sea otter, is a small mammal from the mustelid family. It lives near rocky shores of the Pacific Ocean in South America and swims well in seawater.
The cat otter differs from river otters in that it spends almost its entire life in seawater near rocky shores. It is important for nature because it regulates the population of marine animals and indicates the purity of coastal waters.
