What is the dolphin's breathing system?
Dolphins - like other porpoises and whales, breathe by means of a 'blow-hole' located on top of the head - which leads to the lungs. The animal takes a breath at the surface of the water, and holds its breath so it can dive for fish, before returning to the surface again..
There are six species of porpoises, and porpoises are found in all of the earth's sea-water oceans, mainly near land masses. There are also freshwater populations of the Finless Purpoise. The Harbour Porpoise can often be seen in harbours and ports in the Northern Hemisphere.
Of course, some porpoises live in captivity, in zoos, aquariums and oceanaria.
