The sea lion is a very cute looking animal that lives in the ocean. Sea lions have ears, and if you can see real sea lions, you can clearly see their ears. Sea lions have two cute ears. They not only have ear holes, but also have outer ears, or pinnae. Their ears are on either side of their head, just behind their eyes. Their ears are not degenerated, but they are smaller.
Ears are one of the important features of sea lions, which can distinguish them from some similar animals. For example, seals are similar to sea lions, and they are both mammals and pinnipeds, and seals and sea lions can be distinguished by their ears, because seals have no outer ears, only ear holes.
The above has been introduced, sea lions have ears, not only have ear holes, but also the outer ear has not degenerated. The ears of sea lions can play an important role in their life activities, that is, hearing. Their ears can play an important role when they are hunting or hiding from enemies.
However, sea lions actually have more hearing in their beards than in their ears. Beards have the ability to hear and sound like magic. This is because there are many nerves in the beard of sea lions, which not only play the role of touch, but also receive sound signals from the pharynx and return, playing an important role in hearing. With the help of the sense of touch and hearing of the beard, they can accurately identify objects around them, avoid attacks, locate prey and so on.
