Sea lions are aquatic mammals, sea lions basically live in the ocean. In the process of observing them, many people will find that their bodies are relatively smooth, so they will be mistaken for hairless. In fact, sea lions also have hair. It's just that when sea lions come out of the water, their fur clings to the surface of their skin, and it looks like they don't have any fur. If we look carefully, we can clearly observe the fur of sea lions. Male sea lions, in particular, have a lot of hair when they grow up, especially around their necks.
The fur of a sea lion is usually divided into two layers. The outer layer is called guard hair, which is longer and thicker; The inside layer is relatively soft, relatively fine, is fluff. Most species of sea lions have these two layers of hair. However, because there are many kinds of sea lions, their hair will be different, some sea lions have no fluff, only needle hair.
Sea lions have teeth, and if we can observe them while they are eating, we can clearly see their teeth. Sea lions have multiple teeth in their mouths, some of which are particularly prominent and sharp. The teeth of sea lions can play an important role in their life activities, especially when they are hunting and eating. Sea lions are carnivores, and they can prey on many animals for their own food. And when they catch prey and eat it, teeth can also play an important role.
