They live in water so they developed gills so they could survive in an underwater environment
Well the fishes breath through gills as you know, but the way they breath is that they suck the oxygen out of the water. The way they do this is by: bringing water forth to their mouth which easily then just goes through their body and to their gills, and gets rid of the carbon dioxide, but keeps the oxygen for itself.
it uses its gills
Fish have gills- thy are similar to lungs, but water gets pumped through them. Oxygen dissolved in the water transfers (in the gills) to the bloodstream of the fish, and carbon dioxide gets flushed out.
Because it gets its oxygen from the water through its gills.
There are many symptoms of ammonia poisoning but one of the telltale signs is the redness around gills and tail, more symptoms areGasping at water surface for air.Staying at the bottom of tank.Loss of appetite.First of all you should refill your tank with chlorine free water, your fish should start to get better in about a day, if not it could be you have too many fish for your tank.Hope your fish gets better soon!
Because it doesn't enter their lungs,it gets converted into oxygen through the gills.
The water comes through the incurrent siphon and gets flushed out the excurrent siphon
When sharks breathe they use gills, but the gills do not take in water the extract a type of oxygen and if the water gets filled with oil or other unnatural substances than the shark will die.
Dolphins are mammals, not fish. And mammals breathe with lungs, not gills.
im asking the question, what happen when water gets in brain
The water gets cooler
