Fish hear, but their “ears” are on the inside. Bony fishes detect vibrations through their “earstones” called otolithsotolithsAn otolith (Greek: ὠτο-, ōto- ear + λῐ́θος, líthos, a stone), also called statoconium or otoconium or statolith, is a calcium carbonate structure in the saccule or utricle of the inner ear, specifically in the vestibular system of vertebrates.https://en.wikipedia.org › wiki › OtolithOtolith – Wikipedia. People and fish use parts of their ears to hear.

Can fish hear you talking to them?
The fish will barely notice loud talking or screaming. They will not get scared or spooked. Fish can hear you if they are close enough to you. However, if you are too far away, they may not be able to detect you at all.
Can fish hear noises above water?
In these cases, when the re-transmitted sound from the swim bladder has to go only a very short distance, and so it is more likely to stimulate the inner ear. Many of these species can hear sounds above 1 kHz, and some, like squirrelfish, can detect sounds as low as 20 kHz.
In addition to hearing, these animals also have a keen sense of smell, which they use to find food and mates. They are also able to sense vibrations in the water, as well as the presence of other animals, such as fish and crustaceans.
Can fish hear high pitched noise?
In addition to hearing, fish also have a sense of smell, which they use to find food and avoid predators. They can detect odors in the water, as well as the presence of other fish and other species of fish. Some fish can even smell their own blood.
Can your fish recognize you?
Science has found that fish can recognize their owner’s face even if the owner is standing next to the tank. It is possible for fish to associate something they like with the person who is feeding them.
In a study published in the Proceedings of the National Academy of Sciences, a team of researchers from the University of California, Davis, and the Marine Biological Laboratory in Woods Hole, Massachusetts, tested whether fish could recognize the faces of their owners. The fish were trained to associate a face with a food reward, such as a piece of food or a toy.
After the fish had learned the association, they were placed in a tank where they could see their own faces. They were then released back into the wild to see if they would return to the same tank, or to a different tank. If they did, the researchers would release them back to their original tank and see how long it would take them to return.
In the case of fish that had been trained, it took them an average of five minutes to find their new home, compared to just two minutes for fish who had not been taught the face-recognition trick.
Can my fish see me?
In addition to being able to see their prey and recognize their owners, fish can also see a range of colors since they have a color sense in their eyes. Many species of fish can also see ultraviolet (UV) light, which is invisible to the human eye, but can be seen by fish.
Fish also have a sense of smell. They can detect chemicals in the water, such as ammonia, nitrite, and nitrate, as well as the presence of other fish and other animals. Some species can even smell their own urine.
Do fishes fart?
Most fish use air to inflate and deflate their bladder, which can be found on the sides of their body. The bladder is made up of two parts, the upper part is called the oesophagus and the lower part the urethra. This tube is also known as the sphincter of Oddi.
It is located at the base of your spine and is connected to your bladder by a small tube called a duodenum. When you urinate, urine is forced through this tube and into your stomach and intestines where it is absorbed by your body and excreted in your urine.
Can fishes feel pain?
There is scientific evidence that shows fish can feel pain. Their complex nervous systems, as well as how they behave when injured, challenge long-held beliefs that fish can be treated without any pain relief.
Can a fish drown?
The majority of fish breathe when water moves across their gills. The gills can be damaged if water cannot move across them. They don’t technically drown, because they don’t inhale the water, but they do die from asphyxiation.
“”It’s the most common cause of death for fish in the aquarium trade,” said Dr. Michael J. O’Brien, a professor of aquatic medicine at the University of California, Davis, who has studied the effects of water movement on fish.
Do fish have feelings?
Fish Have Feelings, Too: The Inner Lives Of Our ‘Underwater Cousins’ : The Salt Jonathan Balcombe, author of What A Fish Knows, says that fish have a conscious awareness — or “sentience” — that allows them to experience the world around them in a way that humans can’t. “Fish have feelings, too,” he says.
But they don’t feel anything like we do. They have no sense of self or self-consciousness. And that’s why they’re so fascinating to study.
