Do whales have teeth? Many animals have teeth, and teeth can play a greater role in their life activities. So, do whales have teeth? Many people would think that, as a mammal, whales should all have teeth. However, in fact, this idea is not quite correct, whether whales have teeth can not be generalized.
There are many different suborders and specific species of whales, their appearance and size are different, their teeth are also different. Some examples of suborders can be used to discuss whether they have teeth. For example, the ancient cetaceans have teeth in their mouths, but these whales have been extinct. Another example is the toothed cetaceans, which also have teeth in their mouths, and unlike the first group, they are not extinct. There are also baleen whales, which have no teeth in their mouths after a long period of evolution, and they have special baleen and two nostrils. However, when whales of the suborder Balaenoptera are relatively young, they may still have teeth, which may deteriorate as they grow older.
As mentioned above, some whales have teeth in their mouths, while others have no teeth in their mouths. Whales with teeth may use them to hunt and eat. However, teeth are relatively useless, especially for whales in the suborder of baleen whales, because they usually use sucking when feeding, that is to say, they will suck food and seawater into their mouth together, and then expel seawater.
