Most organisms, except for some such as anaerobic bacteria, respire oxygen. Fish have gills, gills have the ability to take the oxygen out of the molecule H2O.
Fish have gills, which filter out the oxygen from the water. However, they can't breath out of water.
A fish doesn't have lungs, it has gills, so it doesn't breathe in water really.
Fish breathe under water by using their GILLS
to survive
Gills pull oxygen from the water but they can't breathe out of the water because the other chemicals in the air.
Fish breathe underwater using their gills. As water passes over their gills, oxygen is absorbed from the water and carbon dioxide is released. This process allows fish to extract oxygen from the water and breathe efficiently.
Fish breathe oxygen, which they extract from the water with their gills.
Yes. The fish does not use its mouth to breathe. It uses its gills.
No, sharks do not breathe air. They have gills that extract oxygen from the water as it flows over them, allowing them to extract oxygen from the water and breathe efficiently in their underwater habitat.
Fish breathe through their gills. There are usually gills on either side of the pharynx. Gills have thread-like structures (filaments). These filaments exchange the oxygen and carbon dioxide.
They use their gills to breathe under water.
No, saltwater bullheads are fish that require water to breathe using their gills. They do not have the ability to breathe out of water like some other species of fish.
Most fish do... unlike the betta fish they can breathe water and air. Dolphins and whales are an example of ones that breathe only air. Sharks, gold fish and other fish have to breathe water.
Fish have evolved to breathe in the water.
Because fish have gills, and breathe water- and I cant!
Fish breathe underwater using their gills. As water passes over their gills, oxygen is absorbed from the water and carbon dioxide is released. This process allows fish to extract oxygen from the water and breathe efficiently.
No, they are fish and must be in the ocean to breathe.
they have gills
WATER
well yes they do 'breathe' underwater with their gills
whales can breathe underwater that is why they live in water but sometimes they have to come up to breathe like fish
they cannot breathe out of water.
