The fish hasgills that they use to filter from the water the oxygen they need to as you say "breath" ,so when you put them on land there gills are not working anymore by filtering the water for oxygen because there is no water it's as you know just air (oxygen) so there gills are still trying to work but there is no water to filter oxygen for them.
Because fish have gills, and breathe water- and I cant!
From what I know about chemical compunds, there is too much H (Hydrogen) in water for land animals to breathe as there is none in air, or close to it. Also, it doesn't include Argon or Nitrogen.For their counterpart, Water animals can not breathe air(Except for dolphins and lung fish) because they do not reach a sufficient amount of Hydrogen. That's my guess anyway.
they arent because they cant breathe air
Fish have evolved to breathe in the water.
they cant breathe because gills do not support air on land where many other gases are present
they have a mouth just like us, that is what helps them to breathe, but they cant breathe if they are out of water unless they are land animals, which most of them probably arent/
They don't. Antarctica is a land mass and fish need water to be able to breathe.
they will die >what a stupid answer!!
monkeys cant stay on land only fish do
well no. unless u put it in a fish tank!!!
The term "amphibian fish" is a misnomer. Lung fish can breathe air however they are still fish and not amphibians.
No they cant breathe.
