How do dolphins and whales breath under water?
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.
What is mammels?
A mammal it an animal that can only breath in air but does not have feathers like birds. Even Dolphins and Whales have to breath air, that is why they come to the surface so often, they can hold their breath much longer than a human can as well.
Why dolphins and whales do not have gills?
Dolphins and whales are mammals, not fish, so they do not have gills. They breathe air through blowholes on the top of their heads, just like humans breathe through their noses. This allows them to dive deep into the ocean and still come up to the surface to breathe.
How can a dolphin stay under water without breathing?
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!!!!!!!!!!!!!!
What do whales and dolphins Breathe through?
Whales and dolphins are mammals and must breathe air to survive. Furthermore, unlike humans and other mammals, they are 'voluntary breathers', which means they must physically remember to go to the surface and breathe! Depending on the species of whale or dolphin, lung capacity differs. But, they all return to the surface of the water, open a blowhole on the top of their heads (a watertight valve) expel air and quickly take in new before going down below the water's surface. Through their blowhole.
Can whales breathe underwater?
whales an not breath under waterno they can hold their breath under water for long periods of time but come up to the surface for airNo they can't. They take a big breath of air above the surface then they just hold their breath for a long time.
How do dolphins breath to survive in the ocean?
they come up above the water and breath with their blowhole and then go back underwater. they do the same thing as whales so but they are just smaller
Do whales give birth to fish?
No. Whales give birth to whales and dolphins give birth to dolphins. Yah. how do you think whales come to the world if they only give birth to dolphins?
Can dolphins breathe underwater?
No, a whale is a mammal and therefor needs oxygen. Whales breath air at the surface of the water by taking quick breaths through their blowhole. A flap of skin controlled by muscles opens the blowhold when the whale breathes and closes when the whale goes underwater. Whales can hold their breath from 7-30 minutes.
Which type of animals need s to come to the surface zone to breathe?
Whales, dolphins and manitees aka: marine mammals
What is the difference between a fish and a dolphins breathing?
Most fish always have to stay in water. Dolphins come up to the ocean surface for a breath of hair. Dolphins breathe through their blowhole.
The whales and dolphins often come up to the water surface they even release a fountain of water sometimes while moving upwards why do they do so?
That's how they breathe, Mammalian fish such as the whale or dolphin need air to breathe just as much as they need water to swim in. When they break the surface and blow out the water they also take in a breath of air before diving back down
