30 minutes.
Holding your breath underwater is when your head/face is underwater and you do not breath.
No, they must surface to breathe, as they have lungs like all mammals.
A dolphin breathes through its blowhole. When it goes under water it holds its breath when comes out it lets air out and brings air in
Shark are fish and breath water Dolphin are mammals and breath air.
Dolphins can't breathe underwater because they are mammals. They go to the surface to breathe and then hold their breath while underwater
No, however young babies are capable of holding their breath under water.
Dolphins can swim 1,000 feet down before taking a breath of air.
because there gills breave under Walter i it is like holding your breath if a fish is not in Walter
A dolphin is a mammal and not a fish.
A dolphin's blowhole helps it breath while it is in the water.
They aren't. They're really good at holding their breath, but every now and then they have to surface and take a breath or two before diving again.
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!!!!!!!!!!!!!!
