How are aquatic animals able to breathe in water

1.	How are aquatic animals able to breathe in water
Answer» Aquatic animals may breathe air or extract oxygen that dissolved in water through specialised organs called gills, or directly through the skin. Aquatic plants and animals are able to survive in water as water contains 0.7% of dissolved oxygen which is taken inside their body by specially designed organs like gills and by general body surface in plants.
