Otters Have the Most Dense Fur and One of the Most Valuable Fur of All 

Sea otters have the thickest fur of all animals. They have as many as 1 million hairs in every square inch of their most dense body part, and they need every strand of hair as they are the only marine mammals that don’t have a layer of blubber as insulation against the freezing ocean water. However, it is not every part of their bodies that has so much hair. Places such as their paws dont have plenty of hairs, which is one of the many reasons they hold their paws up when sleeping –so to avoid water touching them and to conserve body heat.

Of course too much hair needs good grooming, so the animals spend most of their time eating, sleeping or grooming. Once they are not eating  resting or sleeping, they are usually busy grooming themselves to look good. They groom their furs to remain dry and as warm as possible.

They prefer to use long stands of Kelp which grow from the sea floor all the way up to the surface of the water as a mainstay to sleep without fear of drifting out to the open ocean.

Generally, Otters Eat Too Much Food:

Not just giant otters, all species of Otters love food. They all have big appetites and they require plenty of food to help quick metabolism. They eat about 15-25% of their whole body weight in food per day. To ensure there is sufficient food to satisfy their hunger, Otters can spend about 5 hours every day searching widely for food.

River otters basically eat fish, based on what Defenders of Wildlife revealed. They eat anything and everything they can get with ease. Things like crustaceans, mollusks, insects, birds, oysters, shellfish, crabs, crayfish, frogs, rodents, turtles and aquatic invertebrates while Sea Otters play a significant role in the coastal ocean ecosystem by feeding on a diversity of fish and crustaceans, but importantly, they feed on urchins that eat kelp. Thus sea otters help in keeping kelp forests healthy since urchin populations would be experiencing constant rise while kelp will decline greatly.

Species Found Around the World

Apart from countries like Australia and Antarctica, Otters can be found in almost all the continents in the world . In all, there are 13 different species of Otters found around the world (not just river otters and sea otters). From small Asian small-clawed Otters estimated at 2-3 feet in length, to the massive Otters which are about 5-5.5 feet in length. However, IUCN reveals that 12 of the 13 Otter species except North American river Otters are threatened or endangered and as a result, the population of the animal is decreasing dramatically.
