The marine otter (Lontra felina), also known as the sea cat, is a small, semi-aquatic mammal found along the Pacific coast of South America. It is the smallest marine mammal in the world, and the only species of otter found in South America.

Marine otters are about 87-115 cm long and weigh about 3-5 kg. They have a long, slender body with a flattened head and short legs. Their fur is thick and brown, with a white belly.

Marine otters are excellent swimmers and divers. They can hold their breath for up to 6 minutes and can dive to depths of over 100 feet. They use their webbed feet and tails to propel themselves through the water. Marine otters are carnivores and their diet consists mainly of fish, crabs, and mollusks. They are also known to eat sea urchins, sea stars, and even sea turtles.

Marine otters are social animals and live in groups of up to 12 individuals. They are very vocal animals and communicate with each other using a variety of sounds. Marine otters are an important part of the marine ecosystem. They help to control populations of fish and other marine animals. They are also a popular tourist attraction.

Unfortunately, marine otters are threatened by a number of factors, including habitat loss, pollution, and hunting. They are listed as a vulnerable species by the IUCN.
