? Penguins belong to birds. From the perspective of evolutionary history, they belong to a relatively advanced animal. Many of their body structures and organs are relatively advanced. Studies have shown that most birds have well-developed noses or nasal glands, and penguins are no exception. They have a nose, and the nasal glands are very developed. However, unlike the noses of mammals, their noses are not obvious, but only nostrils, so they are not easy to observe, which may lead some people to think that they do not have noses.
Penguins have noses, and their noses are very important. Because their nasal glands themselves are very developed, they can undertake more important tasks. The first important function is respiration, and the nose of penguins, like the nose of humans, can be used to breathe. Gas passes through their noses, allowing them to exchange gases with the outside world. In addition, their noses also play an important role in expelling excess salt from the penguin's body through nasal mucus. Because penguins often eat animals in the sea, they sometimes have excessive salt in their bodies, which is important for their life activities to expel through their noses.
is the nose of penguins? As mentioned above, penguins have noses, and their nasal glands are very developed and play an important role. The nose of penguins is not very obvious, because their nose is different from that of mammals. They only have nostrils. If you look at the penguins carefully, you will find that there are two slits on their mouths, which are longitudinal, and this is their nose. Although their noses are relatively small, their role is more important, they can be used to breathe, they can also be used to expel excess salt from the body, so that the elements in their body can be balanced.
