What is the breathing process of a dolphin?

Answer:
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..
