Do Sharks Have Tongues?

Are you wondering whether sharks have tongues? Well, you are not alone. This is a frequently searched question on the internet. Do sharks have tongues? Sharks do have a tongue, which is known as basihyal.

The basihyal is a thick section of cartilage situated near the bottom of the mouth. Except for Carpet sharks, Cookiecutter sharks, and Bullhead sharks, it is largely ineffective for most shark species.

Are Sharks Mammals?

Mammalia is a class of mammals that consists of a large number of species. All mammals are warm-blooded animals with milk-drinking offspring. You can characterize a mammal as a species that gives live birth to its young ones, the only exception to this being monotremes.

Monotremes are mammals that lay eggs. The echidna and platypus are monotremes. Mammals produce milk, breathe through their lungs; they are vertebrates and warm-blooded.

Sharks do not meet the most crucial requirements for mammals. They don’t make milk, don’t have hair, and are primarily cold-blooded. 

What are the smallest species of shark?

These species are widespread and may be found in seas all around the world. Here is a list of 5 of the species’ tiniest members.

Dwarf lantern shark

Dwarf lantern shark is the tiniest shark in the ocean, reaching up to 8.3 inches in length (21.2 cm). Little is known about the typical size of these sharks, although most of those discovered can fit inside a human hand.

Dwarf lantern shark

Dwarf Lanternsharks may be found along the shores of Colombia and Venezuela, at depths ranging from 929 to 1440 feet (283 to 439 meters). These small sharks mainly feed on krill.

They are not only the world’s tiniest known sharks, but they are also bioluminescent. That is, they, like other deep water fish, produce light to deceive and capture their prey.

Pale Catshark

The Pale Catshark is the world’s second-smallest shark. In adulthood, this small shark measures just 8.2 inches (21 cm). The Pale Catshark, like the Dwarf Lanternshark, is a deepwater fish that lives at 2148 feet (655 meters) in Indonesia’s Makassar Straits.


They have the appearance of a normal catshark and are reddish-white. Because just one Pale Catshark has ever been captured, nothing is known about them except that they are oviparous, depositing pairs of eggs.

Panama Ghost Catshark

The Panama Ghost catshark is the world’s third-smallest shark species. This small shark may grow 9 inches (23 cm) long and is only found in the Pacific Ocean.

Unfortunately, other than its size and oviparous reproduction, nothing is known about the Panama Ghost Shark.

Scientists estimate it dwells at a depth of 3000-3198 feet (915-975 meters) based on where it was discovered. However, until more is learned, experts can only conjecture on its environment.

Atlantic Ghost Catshark

The following tiny species on the list is the Atlantic Ghost Catshark, also known as the Atlantic Catshark, 9.25 inches (25 cm) in length.

It dwells in the Eastern Atlantic, near the Portuguese island of Madeira, although at what depth is unclear. Scientists believe it is a deepwater shark, similar to other Catsharks. The Atlantic Ghost Catshark is a brown fish that feeds on tiny baitfish.

Green lantern shark

Because the Green Lanternshark is a common bycatch of fishing, scientists have had more time to examine it than some of the other smaller sharks.

The Green Lanternshark is a bottom-dwelling fish that dwells off the Atlantic coast at depths of 1,150 feet (350 meters) and may grow as small as 10 inches (25 cm). It feeds primarily on squid and octopi.

The Green Lanternshark possesses bioluminescent markings that are one of a kind. These black patterns are located along the tail to attract prey.

do sharks have tongues?

Sharks do have tongues. A shark’s tongue, known as a basihyal, is a chunk of cartilage located on the floor of its mouth. This is a bar-like structure that runs along the center of the shark’s chest.

Because a shark’s tongue is not a muscle, it cannot move in the same manner that a human tongue does. As a result, experts believe that a shark’s tongue is developed to provide protection. The ventral aorta, protected by the tongue, is an essential element of a shark’s anatomy.

closeup of shark

Because the ventral aorta is so close to the shark’s mouth, it is protected from significant bits of food. However, it is not the sole function of a shark’s tongue. A shark’s tongue is also used to rip apart its prey and extract pieces of meat from the body.

Though the tongue moves very little, whatever role it plays in ripping into the victim’s flesh is critical. The tongue’s function differs depending on the species.

It may not be necessary for most sharks, but in some species with a bigger and flatter basihyal, sharks may use their tongues to gobble up food with the help of mighty throat muscles.

Carpet, cookiecutter, and bullhead sharks are three shark species that make good use of their tongues. These are creatures that can readily gobble up their prey by creating a vacuum inside their jaws. In reality, the cookiecutter shark is a cutter with a tongue sharp enough to rend the flesh of its prey!

Can sharks taste using their tongue?

The primary function of a sharks’ tongue is to sense flavor. Also, to help digestion and to recognize what is and is not healthy to consume. While human taste buds are located on the tongue, shark taste buds are located entirely differently.

Sharks do not have taste buds on their tongues. They have taste buds in their lips and throat. Non-mammalian vertebrates, in particular, have jaws that protect their teeth as well as their taste receptors.

Woman, Shark, Great White Shark

These are unmistakably sharks, which have numerous rows of continuously growing teeth. In sharks, the area with the absolute maximum concentration of taste lies just below the last row of teeth, both lower and upper jaws.

The taste buds of the sharks mentioned above are concentrated chiefly on their row of teeth, indicating the significant link between biting and tasting. Some research even suggests that taste buds have an essential role in the development of teeth.

Tracking the stem cell in the mouth before the teeth and taste buds evolved in studies of shark teeth development, the cells appear to have moved and even contributed to both structures.

Even after teeth and bite buds have formed, taste-linked cells migrate to the tooth and create an area deep within the jaw.

Sharks’ taste buds are also capable of this. This is to demonstrate that the shark’s tongue is not a taste bud. Also, to show that the shark’s taste buds and teeth have evolutionary relationships and functions.

Can Sharks Move Their Tongue?

The basihyal in most sharks is tiny and immobile. Other species, on the other hand, have more significant, flattened, and moveable basihyals.

They also utilize it often to suck up prey. As previously stated, the basihyal is mainly ineffective, thus moving about the mouth is futile. It is also asserted that the basihyal is not a tongue in any case.

Can Sharks Stick Out Their Tongues?

Sharks’ tongues are connected to the bottom of their mouths. Thus they cannot thrust out their tongues.

On the snout are tiny openings known as the Ampullae of Lorenzini, which aid sharks in detecting the minuscule electrical fields that all living things have.

EPAULETTE SHARKS GUIDE – Description and Care Sheet

This is one of the fishes exhibited at aquarium retailers. Most people consider it to be the finest pet shark for fish tanks. And thus, here are some facts regarding this aquarium beauty that you should be aware of.

The Epaulette Shark, often known as the “walking shark,” is a carpet shark with an extended tail. This kind of shark is usually found in shallow tropical seas. Typically found off the coasts of New Guinea and Australia.

Epaulette shark

Behind the pectoral fins of this shark species are two big black dots surrounded by white markings, similar to military epaulets. As a result, Epaulette sharks got their name.

These species are unlikely to become quite large. They are, in reality, relatively tiny in size. As a result, Epaulette sharks are frequently less than 39 inches (less than 1m) long in maturity. One of the reasons this shark is ideal for home aquarium pets is its tiny size.

Another factor is its adaptability to tight areas. As a result, shark keepers don’t need a massive tank to house the Epaulette shark. These sharks can swim comfortably due to their thin body form.

They most likely like to wander about the bottom of their environment using their paired muscular fins. While wriggling over coral reefs, the fins assist in propelling them. As a result, the walking shark got its moniker. These species are unlikely to become quite large.

While wriggling over coral reefs, the fins assist in propelling them. As a result, the walking shark got its moniker. When looking for food, they generally go to tidal pools. They may also live for a long time outside of water.

This species is on the Least Concern fishes maintained by the IUCN – International Union for Conservation of Nature. Anglers, on the other hand, do not recognize their economic value. Of course, aside from their involvement in the aquarium trade.

What are sharks attracted to?

Shark, Fish, Eye, Animal, Water, Swim

Sharks appear to be drawn to the colors yellow, white, and silver. To avoid shark attacks, many divers use clothes, fins, and tanks in drab colors.

Blood: While blood alone may not attract sharks, the presence of blood in combination with other odd elements can stimulate the animals and make them more likely to attack.

How do sharks breathe?

Sharks do not have lungs, but they must breathe oxygen to exist. Sharks obtain their oxygen from the water that surrounds them rather than from the air they breathe.

Sharks’ breathing mechanism begins with their gills, which they utilize to collect oxygen from water and expel carbon dioxide from their bodies.

How much do sharks eat every day?

Shark, Wallpaper, Water, Sea, Window

Sharks are all predatory in some way. They typically ingest between 0.5 and 3.0 percent of their body weight every meal, as most people have supper every two or three days.

Although their bodies are well-equipped to collect food, they cannot chew adequately and require time to digest.

10 Facts about sharks

It is time to learn some intriguing facts about sharks. Read ahead.

  • The majority of sharks have excellent vision.

Most sharks can see well in low-light conditions, have excellent night vision, and can distinguish between colors. A reflecting coating of tissue called a tapetum covers the rear of shark eyeballs. This enables sharks to see exceptionally effectively in low-light conditions.

  • Sharks have existed for a very long period.

Scientists believe sharks originally originated in the water approximately 455 million years ago, based on fossil scales discovered in the United States and Australia.

  • The tiniest shark species is the size of a human hand!

The dwarf lantern shark is the tiniest shark, fitting into the palm of your hand. These small sharks are rarely found. They dwell deep in the water and may grow to a maximum length of about 8 inches.

  • Some sharks have around 20,000 teeth throughout their lifespan.

Great white sharks have five rows of teeth and can have up to 300 teeth at once! These teeth are constantly replaced, and great white sharks can have over 20,000 teeth in their lifespan.

  • Sharks may travel thousands of kilometres every year.

Some shark species are very migratory, making extensive journeys between feeding areas each year. The longest documented whale shark migration was 12,000 miles across the Pacific Ocean, from near Panama to a region near the Philippines.

  • Some sharks, like us, have warm blood.

While the majority of sharks are cold-blooded, five species are partly warm-blooded: great white sharks, shortfin makos, longfin makos, porbeagles, and salmon sharks.

These sharks can elevate their body temperature above the temperature of the water, allowing them to swim quicker when hunting.

  • Sharks have two additional senses than humans.

Sharks have two extra senses in addition to the five senses that humans have (smell, taste, touch, vision, and hearing).

They use their lateral line (a row of pores extending from snout to tail) to detect pressure changes in the water, which helps them hunt, hide from predators, and travel. They also have an electroreception system, which consists of sensors on their head and snout (called ampullae of Lorenzini).

These incredible sensors can sense even the smallest electrical fields, such as those produced by prey muscle spasms.

  • Sharks have been present in our waters since the time of the dinosaurs.

Sharks have been present for nearly 400 million years in the seas! Sevengill sharks (also known as cow sharks) are among the oldest sharks still living today, having originally emerged in our waters more than 150 million years ago.

  • Every year, over 100 million sharks are slaughtered throughout the world.

This isn’t one of the more entertaining shark facts, but it’s an essential one to mention. Every year, around 100 million sharks are slaughtered, primarily for the shark fin trade. Sharks are also hunted for their flesh and liver oil, and many are captured in fishing nets by mistake.

  • The biggest shark species may grow to be up to 18 metres long.

Whale sharks are the biggest of all sharks, reaching lengths of up to 18 meters (60 feet). Basking sharks, megamouth sharks, tiger sharks, and great white sharks are the next biggest shark species.

Are Sharks warm or cold-blooded animals?

The majority of sharks are cold-blooded. Some, such as the Mako and Great white shark, have a warm-blooded component (they are endotherms).

These sharks can elevate their body temperature to the temperature of the water, but they must hunt with brief bursts of speed.

How do sharks maintain neutral buoyancy?

Being neutrally buoyant means being as heavy or dense as the fluid surrounding you, so you don’t sink or float. Sharks have several characteristics that allow them to be neutrally buoyant.

Sharks have cartilaginous skeletons that are significantly lighter than real bone skeletons. Sharks also have enormous livers that contain low-density oils that offer buoyancy.

While sharks lack the swim bladder that much bony fish have, certain sharks, such as the sand tiger (Carcharias taurus), may suck air into their stomach, providing additional buoyancy.

Do Sharks Have Hair?

It is natural to believe that sharks have hairs on their skin. However, this is not the case. As an aquatic species, it possesses some distinguishing characteristics that will aid in its adaptation to water. This distinctive characteristic is devoid of hair.

Sharks don’t care about their hair because it won’t help them survive in the water. Sharks that live in water require qualities that allow them to swim effectively and with ease. And thus, they have scales rather than hairs.

Their entire body is covered with thick scales. These scales allow them to swim softly and without difficulty. Sharks lack hair because they are not mammals.

Do Sharks Have Ears?

Sharks have a keen sense of hearing and are particularly sensitive to low-frequency sounds. They can trace noises and are especially drawn to sounds generated by injured prey. Their ears are situated behind their eyes on either side of their skull.

These are visible from the outside as two tiny holes. These are made up of three cartilage tubes lined with hair cells and filled with fluid. Sound waves force these microscopic hairs to vibrate, which the brain understands.

Are sharks vertebrates or invertebrates?

Sharks, like humans, have vertebrae. They have a vertebral column (backbone), a spinal cord, and a notochord. This is what distinguishes them as vertebrates, exactly like ourselves.

But don’t be misled by the word “bone.” The distinction is that a shark’s backbone is comprised of cartilage. Our human backbones, on the other hand, are made up of a column of bones.


Hopefully, you are now aware that sharks, like other fish, have tongues. However, they are not the same as what humans and many other animals do. Similarly, they do not serve the same tasks as our tongues.


Do sharks poop?

Every living creature with a digestive system, without a doubt, finds a means to eliminate waste products from the body. There has been video evidence of sharks pooping.

You should be aware that the manner of waste expulsion from a shark’s system varies depending on the shark species. Some sharks are filter feeders, whereas others like hunting and feasting on prey.

Sharks eat a variety of foods due to their varied feeding patterns. These species’ digestive systems and excretion systems differ as well.

Do sharks fart?

Sharks, interestingly, fart. At the surface of the water, they will occasionally suck air. The air then enters their body and exits through their cloaca.

A cloaca is a hole in the body that functions as a urinary, digestive, and reproductive system. The aperture in sharks is found on the ventral side between the pelvic fins.

What to do if a shark is chasing you?

Sharks will feel less comfortable if you keep an eye on them when they circle behind you to take a bite. Maintain your calm and gently back away.

If none of those above methods is practical, you should fight back and target the shark’s eyes and gills due to their sensitivity.

Are sharks blind?

Sharks are colorblind, which means they can’t see many different colors well, but this doesn’t stop them from pursuing their prey since they have a variety of tricks up their sleeve.

Do sharks sleep?

Certain sharks have spiracles that push water across their gills, allowing them to remain motionless. Sharks’ way of sleeping is unlike humans but instead, alternate between active and resting phases.

What color do sharks hate?

Because sharks sense contrast colors, anything vivid against lighter or darker skin might seem to a shark as a baitfish. And thus, it is advised to avoid wearing yellow, white, or bathing suits with contrasting hues, such as black and white.

Can Sharks Smell Fear?

A shark can smell acutely and detect everything that interacts with its sensory cell on its nares. However, this does not include emotions like fear. Nevertheless, keep in mind that sharks do not rely solely on their sense of smell.
