The answer as to why fish do not have tongues is complex. It mostly comes down to their anatomy and the fact that they have adapted over time to survive without one. Fish have mouths filled with teeth and they don’t need a tongue to move food around like humans do.
To understand why fish don’t have tongues, it is important to know that fishes are vertebrates, meaning their internal skeleton provides support, protection and attachment of muscles. The shape and structure of a fish’s internal skeleton directly influences their anatomy and overall shape.
Looking at fish, they have a slender body which is designed to navigate and move through water easily. This shape restricts the size, position and amount of tissues that can be placed in and around the mouth, leaving no room for a tongue and its muscles.
Fish also breathe through their mouth, so a tongue would block and obstruct their airway making it difficult for them to breathe, which would be fatal in the wild. Additionally, the shape and lower jaw structure of most fish make it difficult for them to move their mouth in a way that would make a tongue useful, even if they had room for one.
In the wild, fishes use their mouth to feed largely from the bottom, by sucking and then pushing the food out, which they do not need a tongue to do.
In conclusion, fish do not have tongues due to their anatomy and evolution which limit their mouth shape and positioning of tissues to make room for a tongue, as well as their need to swallow food without obstacles in their airways, and the ability to feed without the need of a tongue at the bottom of the ocean.

Can fish live without tongues?
Yes, fish can live without tongues as long as their other organs are functioning correctly and they are still able to gather enough food. Fish generally don’t use their tongues to eat and are instead equipped with powerful suction devices in their mouths that allow them to quickly gather up small particles of food from the surrounding environment.
While missing a tongue does place some limitations on a fish’s ability to feed and interact with its environment, its other sensory organs can assist with those tasks. Certain species of fish are even born without tongues.
For example, the tongue-less goby is a benthic species which feeds on tiny bottom-dwelling invertebrates and algae. Without a tongue, the fish uses its lips to collect food and debris as it sits on the seabed, which can be more efficient in some cases.
Does a fish tongue feel like a human tongue?
No, a fish tongue does not feel like a human tongue. Fish tongues are generally much smaller and less flexible than human tongues. Fish tongues have small knob-like structures known as “denticles” that help them hold onto food, whereas a human tongue is smooth and flat.
Additionally, the taste buds on a fish tongue are located on the outside of the body and are exposed to the water, rather than being contained like on a human tongue. As such, a fish tongue may feel rough and bumpy, whereas a human tongue is usually relatively smooth to the touch.
Do alligators have tongues?
Yes, alligators do have tongues. Alligator tongues are relatively short and thick, and their tongue is composed of mostly tough but pliable tissue. It does not have the dexterous mobility of other related reptiles, such as the snake, but its tongue does play an important role in helping the alligator sense its environment and find food.
Alligators use their tongues to detect odors, motion, and fluids in the air or water. When the alligator wants to grab prey, it sticks out its tongue to get a better grip on the food and then uses its muscular jaws to finish the job.
The tongue is also used for communicating with other alligators in the water, and some researchers believe it may help with thermoregulation, or controlling body temperature.
Does crocodile have no tongue?
No, crocodiles do have a tongue. While the tongue of a crocodile is quite different from that of humans, it is an important part of a crocodile’s anatomy, and can be seen in the mouths of their snouts when they open to eat.
Interestingly, the tongue of a crocodile is not attached to the bottom of the mouth like in mammals and many other reptiles. Instead, it is attached to the top palate and back of the to the throat, allowing it to move around freely.
This helps the crocodile eat larger things and keep them in its mouth better. In addition to that, it also helps block the movements of prey as it’s swallowed, ensuring that it is properly digested.
Can fish stick their tongue out?
No, fish cannot stick their tongue out like many mammals. Fish do not have tongues of the same make-up as a mammal’s, as they don’t have any bones or muscles within their mouths to allow them to such pucker motions with their tongues.
Instead, a fish has a bony structure in the mouth called a ‘hard palate’, which helps them to create suction when they open their mouths to engulf potential food items. The soft palate, or ‘velum’ which mammalian lungs have does not exist in fish, meaning that their tongues are unable to move independently of their mouths.
Can fish bond with you?
Absolutely! Fish can form bonds with their owners if they are well taken care of, given adequate time to adjust to their environment and bonded to through regular interaction. Fish can get to recognize their owners by sight, sound and movement and can get excited by the owner’s presence.
It is important to handle your fish with care and speak softly although some species may get used to being handled and touched. To create a bond with your fish, talk to it in a soothing voice and make sure to observe its behavior.
Interact with your fish regularly by providing food, providing attention and monitoring their environment. It is beneficial to your fish to take some time each day to observe and appreciate its unique traits, be it its distinctive coloration or playful swimming.
When you create a strong bond with your fish, it can make the fish more relaxed and less prone to stress, allowing it to adopt a healthy lifestyle and even display a more robust appetite.
Can sharks get boners?
No, sharks cannot get boners. Whilst sharks have an internal skeleton, unlike most other fish, their external skeleton is still made up of cartilage and not bone, meaning they do not contain erectile tissue, which is required for an erection to occur.
Additionally, it is believed that the reproductive anatomy of most sharks does not contain the necessary erectile tissues and muscles to facilitate an erection.
What animal Cannot stick its tongue out?
Most mammals cannot stick their tongues out, as the muscles that control the tongue in humans are fairly complex and the same muscles are not found in other animals. Except for a few species such as chameleons, lizards, and snakes, animals generally lack the necessary anatomy to stick their tongues out.
Among mammals, only humans, a few primates, and the New World Sloth bear are anatomically able to stick their tongues out in a humanoid manner. Therefore, most animals cannot stick their tongues out, as the ability to do so is dependent on a more complex anatomy.
Does hooking a shark hurt it?
No, hooking a shark generally should not hurt it. If the shark is hooked, it may experience some soreness in the area around the mouth or jaw, but this should not have any lasting effects. Generally, when a shark is hooked, it is caught with a circle hook, which is designed with a small hole that reduces the risk of inflicting any significant damage to the shark’s mouth or jaw.
The tackle attached to the hook is also typically designed with materials that are designed to minimize any damage to the shark. In addition, if the shark is captured, it should be handled as gently as possible and released quickly to minimize any potential damage.
Once the shark has been released, it should be able to swim away unscathed.
What happens to a shark’s body when it dies?
When a shark dies, decomposition occurs much faster than for many other species due to the lack of bodily protection or insulation that sharks have. Because of this, their bodies decompose at a much quicker rate.
In water, decomposition depends on the temperature, salinity and oxygen levels. For example, in warm, shallow water with a high oxygen level, a shark’s body will start to decompose within several hours.
In colder, deeper waters, decomposition can take place over several days or weeks.
As the shark decomposes, bacteria and other scavengers will consume parts of the body. It is also likely that the remains will be moved due to ocean currents. If the shark is consumed by another predator, the process will be much quicker as bones and tissue are digested quickly.
Once a shark is completely decomposed, the only evidence of its existence is the teeth that may scatter on the ocean floor. These teeth can survive for long periods of time in the ocean and are frequently used in archaeological research and public displays to showcase sharks’ teeth.
What happens if you tap a shark in the nose?
If you tap a shark in the nose, it is likely to cause the shark to become startled and back away briefly. The shark may even swim away altogether. This is a defense mechanism sharks use when they are startled or feel threatened.
In some cases, the shark may act aggressively if it is startled. If a shark is particularly territorial or defensive, it may react to being tapped on the nose by attempting to bite or lunge at whatever is causing the disturbance.
The best way to avoid antagonizing a shark is to stay away from it, and swift movements or contact with the shark should be avoided.
What does a fish’s tongue look like?
A fish’s tongue is generally long and flat, but not all fish’s tongues look the same. The tongue of a common carp, for example, is relatively small and may be hidden entirely within its mouth. On the other hand, the tongues of salmon and trout are large, slim, and pointed, lying flat and covered in small, hard teeth-like structures known as papillae.
Other species of fish, such as cichlids, have a tongue with a deep groove in the middle and a row of sharp tooth-like projections along each side. Some species, such as gar, have a tongue with high ridges and deep grooves that allow them to scrape food off submerged surfaces.
No matter the shape, fish tongues don’t have taste buds on them like human tongues do.
Do fish have teeth on their tongue?
No, fish do not have teeth on their tongue. Fish have structures on the surfaces of their tongues that resemble teeth, but they are not actually teeth. These structures, known as papillae, are made of keratin, the same material that our fingernails and hair are made of.
The purpose of these structures is to help the fish hold on to food while they are eating it. The papillae are often referred to as “taste buds” since they can help the fish to identify their food. They may even have some assistance in crushing or grinding the food in their mouth.
Papillae are also found in various other animals, including ourselves, but in humans they are not typically visible.
Do fish have balls?
No, fish do not have balls. Fish, like other animals, have gonads which facilitate the production of gametes. However, in contrast to mammals, fish do not have testicles which produce sperm in sacs called “balls”.
Fish gonads are usually single organs located near the kidneys that store and release eggs or sperm when needed for reproduction, and are not externally visible like mammalian testicles. Additionally, the gonads in female fish may produce eggs which are then easily distinguishable from the non-existent “balls” of male fish.
