Not like you or I do, but they can still hear. They can even determine the direction and distance from which a sound comes.

Sure they do. You just can't see them.

First, you need some sound facts. All sounds are made from vibrations, so hearing is really a kind of feeling. You can feel these sound vibrations, or waves, when you touch the outside of a ringing bell. Your ears "feel" sound waves, too. Nerve endings in your ears send messages to your brain about the sounds they feel. Sound moves through water the same way it does through air, so a fish actually "hears" water movement.

The moving water flows through the skin at the back of the fish's head into its hidden ears (two hair-lined sacs that contain fluids) and moves the hairs in the lining. Scientists aren't sure, but they think tiny nerve endings attached to the hairs then send signals to the fish's brain.

Most fish can't easily hear really high-pitched or low-pitched sounds. To help hear very low sounds, some fish use a special fluid-filled tube, called a lateral line, as a kind of built-in hearing aid.

A line of tiny holes run along both sides of fish from their head to their back fin. Inside the holes are special nerve cells that sense movement, a lot like how the ear works. It doesn't look anything like an ear, but it helps fish "hear" or feel very low vibrations from moving objects -- like a bigger fish looking for lunch!

They don't have ears. They do however have a lateral line which is a faint line of the sides of the fish that runs from the nose to the tail. This line is filled with water and it detects vibrations in the water. This allows the fish to feel vibrations (sound is a vibration of air, solid, or liquid). They don't hear noises though, as they perceive the vibrations, they "translate" them into chemical signals that the fish can interpret. With their lateral line, they can determine where the "noise" came from. Fish aren't trained by sound, they are trained with signals or vibration sequences. Dolphins, which can be trained by sound, are not fish, they are mammals, and they do have ears. Sharks are fish, and they don't have ears, they have lateral lines that are EXTREMELY sensitive, which is why they are such effective predators.

Yes. They do because you know when you tap the tank they move back. Well that's how they have ears. They can hear and fell the water banging on them. Their ears are behind the skin so that's how you can't see their ears. I've read about fish and I also know that they have ears because some fish are trained to do tricks and you have to tell them what to do and they will do what you told them to do. That how I can prove that fish have ears. But still they can't hear as well as sharks.
