Name two animals which have not gills but they live in water
Answers
Whales,
Dolphins
Turtles
Lungfish In fact gills are actually a common characteristic of fish, sharks (a variation of fish) and a variety of amphibious creatures that enables them to pull oxygen directly out of the water so that they can breathe in an aquatic environment without needing to rise to the surface of the water.
Depending on the species some amphibians can breathe both underwater and on the surface, however most fish and sharks can only breathe underwater and unlike mammals fish would actually suffocate above the surface of the water.
In contrast to fish and sharks dolphins are marine mammals and must come to the surface in order to breathe.
Dolphins are equipped with lungs (like humans and land animals) not gills and would drown if they tried to breathe underwater just as a human would drown if they tried to inhale while submerged underwater.
