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
The aquatic plants release oxygen after photosynthesis. As we all know, the aquatic animals breathe in the oxygen that is dissolved in water. So, the oxygen given out by these plants is very essential for the animals who live there.
most animals need food, water, and oxygen
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.
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.
Water, nature, trees for oxygen and the animals they eat helps a white tiger live
Yes. Marine animals breathe in the oxygen dissolved in the water and thus can live.
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.

Oxygen partially dissolves in water. Respiratory systems of aquatic animals are adapted to get this dissolved oxygen. They have gills for respiration.
Animals require firstly oxygen they cannot live without it for more than several minutes. They require water to live longer than several days.
Amphibians can live both on land and water
