The narwhal is an aquatic mammal that has no teeth at all and thus must rely on suction to feed. The narwhal lives in the Arctic Ocean and feeds primarily on small fish and squid, which are swallowed whole and do not require teeth to tear and chew.
In addition to its characteristic tusk, the narwhal has a strongly developed, sensitive upper lip that it uses to detect navigational obstacles and capture prey. The narwhal is a member of the family Monodontidae, which is the only family in the cetacean order that lacks teeth entirely.

What is the name of toothless animal?
The name of the toothless animal is the aardvark (Orycteropus afer). Aardvarks are nocturnal and mainly insectivorous mammals native to Africa. They typically have a long snout and tail, short legs, and large ears that are used for detecting prey.
Aardvarks are burrowing animals, creating dwellings in the ground. Due to lack of teeth, its diet consist mainly of ants, termites, and other underground creatures. They can also eat fruit and vegetables.
Aardvarks are solitary animals and are rarely seen in the open. They are threatened by habitat loss due to human activities such as poaching and deforestation, as well as increased contact with humans.
Which two animals do not have any teeth?
The two animals that do not have any teeth are the Anteater and the Jellyfish. The Anteater has a long, slender snout and an elongated tongue that it uses to lap up insects. Its saliva contains a form of digestive enzyme which helps to break down the hard shells of the insects it consumes.
On the other hand, the Jellyfish is a primitive creature that lacks a proper stomach, and instead relies on their tentacles to capture their food. Because they have no teeth, they ingest their prey in liquid form, which is then digested within the Jellyfish’s digestive system.
What is the largest mammal with no teeth?
The largest mammal with no teeth is the blue whale. This massive creature can reach lengths up to 30 metres (98 feet) and can weigh up to 180 metric tonnes (nearly 400,000 pounds). Despite its size, the blue whale has no teeth, instead relying on a system of comb-like plates in its mouth called baleen to filtrate krill, which makes up the majority of its diet.
Several species of baleen whales exist, such as the bowhead whale, humpback whale, and minke whale, all of which survive without the use of teeth.
What animal has the weirdest teeth?
It’s difficult to definitively name which animal has the weirdest teeth since there are so many different types of animals with each having their own unique set of teeth. However, some of the weirdest set of teeth have been found in the Australian marsupial known as the Tasmanian Devil.
The Tasmanian Devil has four incisors in both the upper and lower jaws, two large cheek teeth on each side, and no canine teeth. The cheek teeth have grooved cusps and sharp cutting edges, which is a very distinct feature.
In addition, the Tasmanian Devil has very prominent front teeth, which are known as “tusks” or “lugs”. These highly visible teeth help the Tasmanian Devil catch prey and deliver powerful bites. All in all, the weirdest teeth can certainly be attributed to the Tasmanian Devil.
Are any other mammals born without teeth?
Yes, aside from humans, there are several other mammals that are born without teeth. These include the common bottlenose dolphin, the cape fur seal, polar bear cubs, humpback whales, and the East Pacific gray whale.
Additionally, some species of bat, such as the gray bat, Megachiroptera, and Kitti’s hog-nosed bat, are born without teeth. Puppies, kittens, and other baby animals usually do not have teeth until they reach a certain age, and some even undergo a tooth eruption process.
This process involves the eruption of the front teeth first and then the back teeth, which can take several weeks to months.
What type of animal has no teeth?
A number of different types of animals have no teeth, including several species of birds, some species of fish, and some species of reptiles.
Birds are perhaps the most commonly thought of animals when discussing those with no teeth. Some bird species, such as toucans and flamingos, have no teeth at all, while other species have a beak made of keratin which they use to tear and crush food.
Fish also do not have any teeth. Some species, such as carp and catfish, instead have a mouth lined with hard plates or scales which they use to grind up food. Additionally, some fish, such as lamprey, rely solely on suction to feed.
Reptiles also sometimes lack teeth, with certain species of turtles and snakes having no obvious teeth in the mouth. Reptiles will typically have sharp spines in the mouth or a beak that they use to break up food.
In conclusion, there are many different types of animals that have no teeth, including birds, fish, and reptiles.
Do octopus have teeth?
Yes, octopuses do have teeth! While their jaws look more like a beak than traditional mammalian teeth, they actually have rows of specialized, highly-developed teeth. These teeth allow octopuses to capture, tear, and shred their prey, and they are replaced as needed.
In fact, a single octopus can have up to 300 beak-like teeth in its mouth. Octopus teeth are made of chitin (the same material found in the shells of shrimps and crabs) and keratin, and come in a variety of shapes, depending on the species.
For instance, the beaks of tropical octopuses are long, flat, and triangular, while that of Antarctic octopuses are shorter, more pointed, and sharper.
