Sea otters are a kind of cute animals, not only their appearance is very cute, they will also make some looks more cute, silly action. For example, sea otters sometimes rub their faces, and the frequency is relatively high, which is common in some pictures and documentaries. In fact, they not only like to rub their faces, but sometimes cover their eyes, or rub other parts of their body with their paws, etc. Some people may think that this behavior is "cute", but it is not, sea otters rub their faces for a specific purpose, not at will.
As mentioned above, sea otters like to rub their faces. We can often see this phenomenon in the process of observing them. This behavior is purposeful. It is to tidy up their fur. Sea otters are mammals that live in high latitudes, in the North Pacific Ocean and near the Arctic Ocean. Sea otters have a thick layer of warm fur on their bodies, and they also have a thick layer of fat under their skin, which is their body structure evolved to keep warm. When sea otters dive into very cold water, their fur can keep the ice out.
If their fur is stained with dirty things, or because it has not been tidied up for a long time and appears messy, it will seriously affect the role of water resistance of their fur. If they go to the sea at this time, the sea water may invade their bodies through their fur, the heat will soon be lost, and sea otters may be frozen to death. Therefore, it is very important to tidy up the fur regularly, and rubbing the face is also the purpose.
