Dolphins don t breath under water. Mammals breath air. Every 15 min they go out of the water to breath
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!!!!!!!!!!!!!!
Dolphins can't breathe underwater because they are mammals. They go to the surface to breathe and then hold their breath while underwater
They don't. When submerged, dolphins hold their breath.
Spotted dolphins can hold there breath under water for 7 to 8 minutes
because they are mammals and need to breath but they can underwater for a long time
Dolphins are mammals which means they give live birth, under water!
Dolphins have gills so they can breath when they are under water
Sharks are fish, and breathe with gills. Dolphins are mammals, breathe with lungs, and can't breathe underwater. They breath at the surface, then hold their breath - which they're really good at - while diving.
No mammals can breathe underwater. 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.
No, no mammals don't have gills, and can't breathe under water. Mammals have lungs, breathe air and have to hold their breath when diving.
Dolphins breathe with lungs. Because they have a blowhole on top of them.Dolphins are mammals and like other mammals they have lungs. They must come up for air periodically.with lungs or gills
Seals can't breath underwater, so they have to come to the surface for air.
