People often wonder, do goldfish have hearing? The answer to this question is yes! Many people are often curious whether goldfish can smell, taste, touch, how they eat, do they sleep and can goldfish hear. Goldfish can hear but it’s not like us how we have ears in through which we are able to hear sound. On goldfish they don’t have ears on their outer body like us, instead they have hearing from within their body.
Your probably wondering how do we really know they can hear? Well if you go to a tank and you tap on it you will see them dart away as they become frightened and scared. They heard it! Goldfish hear through an inner organ which is located within the head of the goldfish. It’s not the same as in humans as we have a main sensory organ called the cochlea and goldfish do not have that. Now with goldfish since they have no cochlea, they have something different within called the otolith which is a hard stone. Now remember when I mentioned above about tapping on a golfish aquarium or tank that the goldfish can hear this, well the otolith is what actually detects sound.
Goldfish hearing is all heard through vibrations which sound vibrations are transmitted through the water and the otolith detects it. It’s pretty neat understanding the anatomy of fish and how they react and hear things.
So goldfish can hear to answer everyones question. I know I did some research on the cochlea and we hear very much the same actually. There is fluid within the ear that has small hairs that move with sound or vibration in which then the brain comprehends into sound. It’s pretty neat actually and goldfish hear through the water in which vibrations goes through the fish’s body to the otolith, neat to know how sound is perceived. Just don’t tap on fish tanks really as it can kill fish through vibrations. It can cause fish stress and other things to occur, they can hear so don’t do it just to test the hearing theory and care for your goldfish.
