Do fish smell or hear?

  • We are currently upgrading MFK. thanks! -neo
Yes,yes,yes,fish can taste,smell&hear.The lateral line is of course the way fish hear,they actualy feel vibrations in the water instead of hear as we know it.Fish have a remarkable sense of smell,take the bull shark,they can smell a drop of blood in millions of gallons of water comming from hundreds of miles away, and taste,of course they taste.any body who has ever kept fish can attest to the fact that they will attempt to eat most particulates either on the bottom or floating around the tank,and if it does'nt taste good they will spit it out.

Also, what is the latteral line (and this isn't a stupid question cos i don't know the answer)?????
Ok, the lateral line can be seen running lengthways down the body of the fish from the back of the gills to the base of the tail. It is basically a sense organ used to detect movement in the surrounding environment, and does this by the use of receptors called neuromasts .
 
WIKIPEDIA defines Lateral line as being a sense organ used to detect movement and vibrations in the surrounding water.Vertabrates such as sharks use lateral organs modified into electroreceptors to detect magnetic fields
 
Yes, Yes, and Yes. Fish do hear...but some use their lateral line more than ears. EXAMPLE: If you tap on the glass of my tank with Mountain White Cloud Minnows, they scatter because they have a well-developed lateral line. My Mosquitofish, on the other hand, don't, so their reaction is less so. But they do hear the tap, and if they are near the surface will jump.
During feeding time, my fish sample everything in the water. If a tankmate expels waste, they will sample it (eeeeew!!) and spit it out because they don't recognize it.
And on smell, you've never heard about Sharks being able to detect blood if the part ratio of blood to water is 1/1000000? (Before I was an aquarium fish freak, I was an absolute Shark freak.)
Also I did a smell experiment with my Mountain White Cloud Minnows. I put alot of food in a net and hung it so that the pocket of the net is in the water. They started zigzagging, just like they were picking up a scent trail frm food, just as they do when I feed them.

Fish can't detect electric fields with their lateral lines, although sharks can with nose pores called Ampulae of Lorenzini:grinno:. (I'll take 2 servings :ROFL:) The way I understood lateral lines is that it's just a place where normal nerve endings pile up.
 
absolutely yes to all three. like other posters have stated.
 
The lateral line is a line running across the body of a fish which you can see if you look closely... It kind of looks like little holes in a line. The line is like our ears.
