18 minutes ... Dolphins can't breathe underwater because they are mammals. They go to the surface to breathe and then hold their breath while underwater...
Dolphins are conscious breathers, which means they have to think about every time they want to take a breath. They respire through a nasal opening called the blowhole, which is located on the top of their head. When resting, their blowhole remains tightly shut. They are able to hold their breath for an average of 4-5 minutes and a maximum of about 10 minutes. Dolphins are efficient breathers. They are able to exchange 80% of the air in their lungs with each breath, while humans are only capable of exchanging 17%.
No mammals can breathe underwater at all. All mammals, including sea mammals, must breathe above the surface of the water. This is why marine mammals such as dolphins and whales frequently come to the surface.
