Aquatic animals, whether vertebrate or invertebrate, live in water during most or all of his life. In the group of invertebrates we can be found cnidarians. This group consists of jellyfish, anemones, corals, and hydras. For the part of vertebrates we found all fish to breathe using gills and lungs using, like dolphins or whales.

As they breathe:

Aquatic animals often make the exchange of gases with water. The amount of oxygen containing water is less than that of air. Breathing animals in this environment have adapted to these conditions, and need very effective systems able to extract oxygen from water.

Natural environments and the animals that live in them can be classified as water (water) or ground (earth). Animals that move rapidly from water to land and back are known as amphibians. When animals live in water, they undergo special adaptations that help them survive in an aquatic habitat. The more time you spend on the water, the quicker they adapt to their new habitat. On our planet we found many ways in which an aquatic animal can adapt to their habitat.
