They have evolved several specialized systems that makes them very good at holding their breath. But eventually, they have to surface to breathe.
they have spechial nostrils
Yes. Alligators breathe with lungs.
Yes. goldfish breathe water so if a goldfish is out of water it cant breathe so it will suffocate
no, they cant stupid
the majority of oxygen is found in water therefore you cannot breathe the oxygen in water
The reason you cant breathe under water is because people is made to breathe oxygen, water composes oxygen.
Because fish have gills, and breathe water- and I cant!
they arent because they cant breathe air
They have all organs like we do. Eyes, heart, lungs, stomach etc.
cause you don't have gills but we have lungs to breathe the oxygen in water
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/
With lungs, pretty much like you and I.
yes they do and they cant stop in water or they will suffocate
