henward Posted January 5, 2008 Report Share Posted January 5, 2008 just wondering can fish generally smell i know most fish do, but some i dont know can jardinii and silver aro smell things? or do they taste? cos sometimes my jar is hungry, i put a prawn, eats it up then i put ox heart, then it goes near it, about to strike, and swims away seemingly doesnt like the smell, i mean it cfould see it before going close but it goes close anyways, but when it got close to its mouth, it ignores it.

Caryl Posted January 5, 2008 Report Share Posted January 5, 2008 Yes fish have a sense of smell. Salmon apparently have a highly developed one. Quote Link to comment Share on other sites More sharing options...

firefish Posted January 6, 2008 Report Share Posted January 6, 2008 Salmon have a good sense of smell so they can return to their birth place to breed and they do this through the sent in the water Quote Link to comment Share on other sites More sharing options...

Silvia-15 Posted January 6, 2008 Report Share Posted January 6, 2008 Salmon have a good sense of smell so they can return to their birth place to breed and they do this through the sent in the water thats only a theory, some people think they follow the stars, follow the currents, or follow the earths magnetic field no one really knows DUN DUN DUN 8) but anyways, my ornates definately smell...

Caper Posted January 13, 2008 Report Share Posted January 13, 2008 Hmmm...Sam, my blind goldfish, doesn't appear to have a great sense of smell. I mean when I put the food in he doesn't go directly at it so that leads me to believe it's not so great...but then I haven't asked him either :lol: Caper Quote Link to comment Share on other sites More sharing options...
Ira Posted January 13, 2008 Report Share Posted January 13, 2008 Have YOU ever put on a blindfold, tied your hands behind your back and tried to find your dinner? To make it more realistic, put a couple fans blowing around in the room. Quote Link to comment Share on other sites More sharing options...
henward Posted January 13, 2008 Author Report Share Posted January 13, 2008 wll the reason ask is that marine fish i know has a sense of smell shark can small blood a mile away i dont even know how that is possible. i mean smlling a scent in a gas form is something else but smelling blood amile away in water, how does the blood diffuse tat fast through liquid? dunno so in theory i dont know how that works just wanted to know if jardinii and other fw fish cn generaly smell Quote Link to comment Share on other sites More sharing options...
Ira Posted January 13, 2008 Report Share Posted January 13, 2008 It doesn't diffuse that fast. It diffuses basically at the same speed as the water currents. If the current is 5mph then it's going to diffuse at 5mph and take the shark that's a mile away 12 minutes to smell it. Quote Link to comment Share on other sites More sharing options...
henward Posted January 13, 2008 Author Report Share Posted January 13, 2008 so how does it that scientists claim that sharks smell blood miles away. thats rubbish cos correct me if imi wrong - but if the blod particles andsmell is nclosd in the water, and hence takes the same speed as the water to diffuse, how can they smell it miles away, they can only smell it when the blood is right on their face when the water takes it to there example, having a piece of chicken 100 metres away, and having it right by your nose. strange, some scientists probbly make claims jsut for the hell of it Quote Link to comment Share on other sites More sharing options...

Ira Posted January 13, 2008 Report Share Posted January 13, 2008 To begin with, I doubt that 1 mile away is a number given by a scientist. It was probably from a reporter. And of course, reporters are basically idiots. If a scientist was giving the number it would likely be something like, "Sharks can smell blood at a concentration of 1 part per billion." or similar.

Naz_Nomad Posted January 14, 2008 Report Share Posted January 14, 2008 Here's what my little book says about fishy smells... "Smell and Taste Responding to chemicals diffusing through the water is a highly specialised sense in fish, since it is vital for communication and discovering food. The distinction between smell and taste is difficult to make; both senses are best described simply as 'chemoreception'. There are specialised chemoreceptor sites concentrated in the nasal openings, scattered in the mouth, around the head and, in some species, even over the body. " It goes on, of course, but that little extract says that fish have an excellent sense of smell, which in water is more or less the same as taste.

me love fishy Posted January 14, 2008 Report Share Posted January 14, 2008 sharks can also feel vibrations of distressed fish in the water, so maybe as they are moving towards the vibrations they get the smell of blood. I mean they do have a super sensitive sense of smell but its not the only sense they use to find food. Quote Link to comment Share on other sites More sharing options...
Cricketman Posted January 14, 2008 Report Share Posted January 14, 2008 sharks such as the hammer head and sandshark prey on fish that they find under the sand. other sharks such as mako can detect the heartbeat of a struggling or injured fish in the water column. they do this by using a 6th sense, the sense of being able to detect minute electrical charges produced by heart or other muscles by use of organs scattered around thier head called the "ampullae of Lorenzini" located at teh base of pores that lead to teh surface of the skin. these can be seen in closeups of sharks heads and look like a "5 o'clock shadow". the hammerheads head shape in fact is due to this extraordinary 6th sense, withthe underside scattered with these pores in order to detect the heartbeat of hiding fish under the sand. it is also this sense that is behind technology such as teh "shark shield" that was designed to irritate the ampullae and to ward off shark attacks. sharks also have a heightened sense of "smell" which is directly connected to thier sense of taste, and some sharks such as mako, bronze whaler, and great whites use this sense of "smell" to find injured prey or the smell of prey animals. they tend to zig-zag up the scent trial into the current until they find the source. this has been demonstrated time and again by studies and by everyday fisherman. even though the exact parts per million will differ between species depending on thier feeding style. any questions?

Taste and smell aren't totally seperate senses in us air breathers either... Quote Link to comment Share on other sites More sharing options...
livingart Posted January 14, 2008 Report Share Posted January 14, 2008 human beings senses are generally pretty cr*p compared to the rest of the animal kingdom Quote Link to comment Share on other sites More sharing options...
henward Posted January 14, 2008 Author Report Share Posted January 14, 2008 thats true some animals entirely communicated through smell and chemical scensing. but, one thing humans have that most animls though, is logical methodical analysis. most animals except primates dont have the advance logic we have. Humans are the only animal that can prety much almost adapt to ANY environment, and survive. i guess thats a plus Quote Link to comment Share on other sites More sharing options...
