Spotted dolphins can hold there breath under water for 7 to 8 minutes
Forever
as long as they want until they need to spout the water
about 4 years
They don't. When submerged, dolphins hold their breath.
If you mean how long can dolphin stay under water, it's about 20 minutes for a common bottlenose dolphin. I am not sure about other species of dolphins.
It is beacouse of their blowholes
Here are some common dolphin types. Bottlenose Dolphins Orcas Long Beaked Common Dolphin Spotted Dolphin
Dolphins and Whales can stay under water for so long is because they have blowholes to come to the surface and get air. They can stay under water for quite a while before they need another breath at the surface:) Need more help... Just ask!!!!!!!!!!!!!!
They don't. Dolphins and whales breathe air just like we do. They can hold their breath for a long time, but they come up to the surface to breathe.
No, they have the ability to hold their breath for long periods of time. (ie. whales, dolphins, etc.)
an Atlantic spotted dolphin lives to about thirty in captivity, but i don't know how long it lives in the wild
Evolutionary theory is that dolphins were a land animal which returned to the sea some millions of years ago. They can breathe on the surface because they have a blowhole which allows them to breathe air. They cannot survive for long out of water because their physiology requires that they be suspended in water and because their skin dries out quickly.
