Whales are marine mammals that live in the oceans and seas. The blue whale tops the list as the biggest animal on Earth, reaching lengths of up to 100 feet and weights of up to 200 tons. The family of animals known as cetaceans, which includes dolphins and porpoises, includes whales.

Do whales have teeth? No, not all whales have teeth, to quickly answer your question.

Marine mammal species are divided into two groups by scientists within this family: those with teeth and those with baleen plates. Investigating whale dental patterns reveals fascinating details about the traits and behaviors of these animals.

Which Whales Have Teeth?

Whales that possess teeth employ them to attack and eat their prey. All dolphins and porpoises have teeth, as do some whales. The toothed whales family includes about 65 different species. The blowhole on a toothed whale is singular. Compared to baleen whales, these whales typically have smaller size ranges. The largest toothed whale is typically the sperm whale. The use of teeth varies among whales in this suborder. While some of them chew their food, others simply swallow their prey whole. Particularly during the mating season, some whales that have teeth use them to show dominance. The number of teeth that whales have varies depending on the species. While some whale species only have one or two teeth, others may have as many as 240 teeth or more. Dental patterns can differ. In some toothed whale species, both the upper and lower jaws are equipped with teeth. Only the lower jaws of other whales are equipped with teeth.

Toothed Whales And Hunting

In order to hunt, toothed whales employ a variety of tools. As they hunt, these whales use vocal calls and visual cues. They could team up to encircle a school of fish when they were out hunting as a pod. Then, they might attack after gathering their prey into a small group. In search of the weakest prey to grab, other whales may swim straight through a dense pack of prey. Another hunting strategy involves encircling the prey so that it cannot flee before striking. One type of toothed whale is the sperm whale. To catch a meal, these whales have been seen diving up to 3,000 feet.

Hunting And Echolocation

To find prey, toothed whales use echolocation. The whales use echolocation, which involves making sounds, to locate food and navigate underwater. The air that passes through the sinuses of these whales creates sound. The whales’ middle ear and jaw pick up the echoes that are produced when the sounds strike objects. The whales can learn where their prey is by doing this. Echolocation’s high sensitivity may even be able to provide precise information regarding the size and shape of prey. Working in groups, whales can hunt together by tracking and attacking as a unit using echolocation.

Which Whales Don’t Have Teeth?

Whales with baleen have no teeth. Baleen whales have two blowholes and are typically larger than toothed whales. These whales have unique baleen plates with bristles that serve as their dental needs in place of teeth. The bristles resemble comb teeth. Depending on the type of whale, some bristles are fine and others are coarser. Baleen whales swim toward their prey while holding their mouths open wide to consume it. They do this to bring seawater into their mouths as well as large groups of fish or other creatures. By pressing their tongues against the bristles of their baleen, the whales then filter out the prey and expel the seawater. While allowing water to pass through, the bristles successfully prevent the animals from escaping. Because of the way baleen whales catch their prey and filter out the unwanted seawater and sediment, some scientists refer to them as “filter feeders.” Baleen whales can’t chew their food because they have no teeth. The animals are instead swallowed whole by them. This is why these whales typically hunt small prey that they can easily swallow. For instance, the typical size of blue whale prey is less than two inches. Comparatively speaking to toothed whales, baleen whales have very small throats. They favor small prey for this reason as well. Echolocation is used by baleen whales as well, but not in the same way as it is by toothed whales. Baleen whales are thought to produce songs to communicate with one another, according to scientists.

Why Do Baleen Whales Lack Teeth?

Everything depends on their diet and food-gathering techniques. Whales don’t eat vegetables, which require a lot of chewing as you and I do. Small fish, so-called krill, prawn-like creatures, and microscopic organisms known as plankton make up the majority of their diet. Antarctica-sourced krill.

These are tiny, measuring only a few centimeters in length. Vast swarms of Vanessa PirottaKrill, which are only a few centimeters in size, can be found in the ocean. A busload, or 6,000 kilograms, of krill, can be consumed by a blue whale each day. Fortunately, most baleen whales have mouths that are as big as cars—they have very wide mouths. Scooping them up in one enormous mouthful is the best method for eating all of these tiny creatures at once. Baleen whales expand their throats, which have grooves that extend to their stomachs and widen their mouths.

As a result, the whale can expand their mouth to an enormous size, like an expanding slinky, and scoop up large quantities of krill and water at the same time. A large enough elephant could actually fit inside some whale mouths.

How Does A Baleen Whale Eat Dinner Without Teeth?

First off, since the whale wouldn’t fit in the kitchen, dinner would have to be served outside.

Both krill and fish would be necessary for mom or dad. You will only be using your mouth to eat tonight, so forget about knives, forks, and any other table manners.

The crazy part is here, though. Your whale friend would open its mouth and widen its throat when dinner was ready. The entire kitchen table, including you and your family, would likely be covered by this because it would be so wide.

Talk about an unwelcome, odorous, and blubbery dinner guest!

What Happens To All That Water?

Imagine a lot of straw broom bristles; that is how long strands hang from the top of the mouths of baleen whales. The substance that makes up these strands is keratin, which is also found in your hair and nails.

These bristles are used by the whale to push seawater out while securing krill in its mouth. Similar to a sieve that separates spaghetti from the pasta water.

Some whales—such as the humpback whale—are skilled hunters and may blow bubbles from their noses to create nets around their prey.

These bubbles gather the fish together so that the whale can swallow them all at once.

The Bottom Line

Unquestionably, the blue whale is the biggest animal alive today. They glide gracefully along the ocean in their enormous, slender, narrow bodies, occasionally swimming up to the surface to breathe.

More information on whale teeth and the fact that not all whales have teeth is now clear to you. I hope this article will be helpful to you.
