Mammals cannot breath water. Dolphins, whales, seals, walruses, and other aquatic mammals all have lungs and breath air. They seem as if they are breathing water because of the assumption that they have to breath as often as we do. However, aquatic mammals can actually hold their breath much longer, ranging from around 10min for a walrus to over an hour for some whales.
The reason they can do this has to do with the construction of their lungs and the Diving Reflex, which slows heart rate (among other things).
Mammals, such as whales and dolphins, have to hold their breath while underwater. They all have lungs and breath air and would drown if they tried to breath underwater. However, they can hold their breath for a long time (over an hour for some whales).
mammals cant breathe underwater only some of them like a beaver and the family...
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.
Dugongs are mammals, and mammals CANNOT BREATHE UNDERWATER, but they can hold their breath for a few minutes.
dolphins are mammals, not fish. They have lungs, not gills, and breathe air.
They are mammals. Amphibians are cold-blooded animals that can breathe through gills underwater as well as using lungs on land. Lions are warm-blooded and cannot breathe underwater.
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.
Dolphins can't breathe underwater because they are mammals. They go to the surface to breathe and then hold their breath while underwater
She wear's it because mammals can't breathe underwater.
Orcas - killer whales don't Breathe under water. They are mammals and Breathe air with lungs. They hold their breath when diving.
Narwhals are whales, and whales are considered mammals, and mammals can't breathe underwater. Therfore, a narwhal must breathe air to prevent from drowning, and to do so, they (and all the other kinds of sea mammals) must swim up to the surface every few minutes to breathe air.
Dolphins are mammals, they Breathe air. If trapped underwater they eventually suffocate or drown.
Platypuses breathe air. All mammals, including marine mammals such as whales and dolphins, must breathe air.Platypuses usually hold their breath for one to two minutes while they hunt and feed underwater, and they are capable of staying underwater for up to eight minutes if undisturbed. They must make hundreds of dives every day in order to find enough food, as they cannot live or breathe underwater.
