Baleen whales have no teeth;
Do whales have hair for teeth. Instead of teeth, baleen whales have a substance called a “baleen plate.” since they have this plate, they must hunt and eat their food differently than toothed whales do. Risso's dolphin also possesses vestigial teeth just beneath the skin (sylvestre, 1993). The largest whale tooth is found in the male narwhal:
Human hair is made of keratin. It continues to grow as long as the whale lives, because it wears down at its tips so it needs to be replaced. The baleen is actually made out of keratin, which is the same protein that makes up human hair and fingernails.
While it's not immediately obvious, whales do have hair. Its long tusk is actually the upper left canine growing in a spiral, piercing the upper lip and reaching up to 2.7 metres long. However, the ancestors of baleen whales had teeth.
Sperm whales have teeth in their bottom jaw, but none on the top, so they cannot bite or chew. These whales don’t have any teeth but instead they have baleen (which is also known as “whalebone”). We know this from two lines of evidence.
Living whales fall into two groups: Some, like orcas, use their teeth for grabbing while the long tusk of a male narwhal acts as a sensory organ and may help them “taste” the. 'for instance, humpback whales are filter feeders, meaning they have hundreds of plates of baleen in their mouth instead of teeth.
First, close living and extinct relatives of baleen whales have teeth. These bristly baleen plates filter, sift, sieve or trap the whales’ favourite prey from seawater inside their mouths. Yes, some species of whale do in fact have hair.
Baleen is made out of keratin, the same protein that makes up our fingernails and hair. Baleen whales have keratin baleen plates instead of teeth. Like all mammals, whales have body hair, and nurse their young with milk.
Because their heads are enormous—making up as much as 40% of their total body mass—and they have throat pleats that enable then to expand their mouths, they are able to take huge quantities of water. The oldest whales had teeth. Baleen is made of keratin, like our fingernails and hair.
Baleen whales include many of the largest whales in the sea, such as the blue whale. Hundreds of overlapping baleen plates grow downwards from the roof of the whale’s mouth, like curtains. 'but baleen whales do grow teeth in the womb.
Carlos mauricio peredo, national museum of natural history predoctoral fellow. The baleen plates look like hair that dangle in the mouths of whales, like a hairy curtain, or like a hairy comb. There are over 80 species of whales, and hair is only visible in some of these species.
Toothed whales (including dolphins and porpoises) all have teeth but the number, size and position, and even purpose of their teeth, varies from species to species. Due to the fact that humpback whales are considered to be mammals, then yes, they do have hair, whales and dolphins are some of the many mammals that call the ocean their home. The bristles of baleen whales are often said to resemble the teeth found on a comb and can be very thin and fine depending on the species of whale.
In some adult whales, you can't see hair at all, as some species only have hair when they are fetuses in the womb. It’s much more likely that baleen whales simply lost teeth than that all of those different groups independently evolved teeth. Unlike the toothed whale species baleen whales do not possess teeth but instead are born with baleen plates that have bristles attached to them.
Teeth do not seem to be essential however, as whales have already been found with missing or severely worn teeth, or with fractured jaws, but which were nevertheless able to feed.
