Most get it from the dissolved oxygen in the water through their gills. Others, such as sea mammals, dolphins etc, need to surface to breathe

What is biological imortance of air dissolved in water?

How do animals live underwater?
All animals that live underwater must obtain oxygen in one way or another. Fish for example have gills that move water past their blood vessels allowing oxygen to diffuse into their bloodstream. Mammals and some other animals must return to the surface of the water to breath in oxygen. While they are under water they eat many things, other animals, algae, and detritus.
Why creatures can live in water?
If by creatures, we mean animals, they require oxygen to survive. Humans get oxygen from the air by using their lungs. Underwater animals can get oxygen directly from the water (water contains dissolved oxygen) by using their gills. Other animals don't have gills (like dolphins) so they live underwater but come up to the air every now and then to get their oxygen. Life in general is very good at living in water. For billions of years, creatures were ONLY able to live in water. Land animals, like us humans, evolved later to live on land so now we are so poorly adapted for life underwater that it would kill us.
How are mineral salts and oxygen beneficial for aquatic life?
Yes. Marine animals breathe in the oxygen dissolved in the water and thus can live.
What helps a white tiger live?
Water, nature, trees for oxygen and the animals they eat helps a white tiger live
Fish breathe what?
Fish, like all animals, require oxygen to live. They get their oxygen by filtering it out of the water using their gills, so you could say that they breathe water.
What animal need in order to live?
