If you’ve ever been to an aquarium, you’ve probably seen a fair share of sharks. You might have noticed that their mouths look a little different than humans.
They have thousands of teeth, so it’s hard to get a closer look at their tongue. You might be wondering: do sharks have tongues?
Sharks have tongues, but they are not functional in most species of sharks. Their tongues are a small piece of cartilage called a basihyal that’s located on the floor of their mouth. Some species have a larger basihyal that helps suck in prey. But this organ does not have strong taste buds like a human tongue.
Do sharks swallow their food whole?
Yes, most sharks swallow their food whole or break it into pieces and swallow the pieces whole. Because of their strong digestive system, they don’t need to break down the food into small pieces.
Do sharks have teeth?
Yes, all species of sharks are born with teeth. They are made of incredibly strong material called calcium phosphate. A shark’s teeth grow in rows, and most sharks have five to 15 rows of teeth.
Do shark teeth grow back?
Yes, shark teeth grow back sometimes in a matter of days. Shark teeth are not attached to a root in the mouth like in humans. So the teeth fall out easily and are regenerated quickly. Sharks can lose about 30,000 teeth over the course of their lifetime!
Do fish have tongues?
Yes, fish have tongues, but they are not prominent muscular structures like in humans. For fish, the tongue helps transport food through the mouth and to the digestive tract. Most fish have a small piece of cartilage called a basihyal at the floor of their mouth. This structure can also facilitate breathing, moving water to the fish’s gills.
Do sharks have taste buds?
Yes, sharks have taste buds, but they are not as developed as humans. On most sharks, the taste bud receptors are small bumps along the inside of the mouth.
Do sharks have ears?
Yes, but the ear is inside their body, unlike the outer ears of humans. A shark’s ear is located behind its eyes, inside two small holes. A shark can hear prey from up to 800 feet away. They can hear low frequencies much better than humans.
Are sharks apex predators?
Yes, sharks are apex predators. This means that they are the top of the food chain, not hunted by many other predators. Most sharks feed on fish, seals, crustaceans, and even other sharks. Apex predators are important to a functioning ecosystem. They keep prey populations in check.
Without predators, prey populations would continue to grow and eventually they would have trouble finding food and water sources. Populations will inevitably become crowded and prey would die off due to scarce resources.
On the other hand, too many predators means that the predators would have difficulty finding food. This means they would have to relocate or otherwise die to starvation.
Can sharks live in freshwater?
Yes, but most sharks survive in saltwater environments. They need a high amount of salt for their vital organs to function. A couple of species of sharks can survive in freshwater: the bull shark and speartooth shark.
Are sharks warm or cold blooded?
Most sharks are cold-blooded, also called endothermic. This means that their body temperature matches the outside environment – in this case, the surrounding water. In contrast, humans are endothermic. We maintain an internal body temperature regardless of the external environment. A select few sharks from the Lamnidae family are warm-blooded or endothermic.

How far away can a shark smell a single drop of blood?
Sharks can smell a drop of blood from about a quarter-mile away. A shark’s sense of smell is much stronger than humans, but it’s often exaggerated in movies. Most sharks don’t have this strong of a sense of smell.
How do sharks smell?
Sharks smell through two small nasal cavities called nares, below its snout. While humans use their nose for breathing and smelling, sharks use their nose exclusively for smelling. Water travels into one nasal opening and out the other. There are sensitive smell receptors inside the nose that help the shark smell its prey.
Are sharks interested in eating humans?
Sharks are not interested in eating humans. Humans are made up mostly of water and have a lot of bony structures, which is not very nutritious for a shark. They prefer to dine on softer prey like seals, dolphins, or other similar species. Most shark attacks on humans are due to the shark’s curiosity. They want to test to see if the prey is food or not.
That’s all for our post ‘Do sharks have tongues?” The short answer is yes, but they are not as prominent as a human tongue. In most sharks, the organ doesn’t have an important function. Some species use it to help swallow food.
