Whales are mammals and must breathe air to survive but , 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, 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) to expel air and quickly take in more before going down below the water's surface.
How do whales stay under water for an hour or more on a lungful of air?
The answer is: they do not. Whales expel the air from their lungs shortly after diving so they are no longer buoyant. The rest is squeezed out by increasing water pressure. They are able to remain under for so long by oxygenating their blood because of their increased lung capacity.
When a whale dives oxygen is only sent to the parks of their body's that need it the most like the brain Muscles for swimming and their heart, the rest of the body must wait for the dive to Finnish until it can get its oxygen, unless the dive is a very long one so the animal gives the other parts of its body like the stomach a little bit of oxygen every 20 minutes or so.
Human beings can hold their breath under water for an average of one minute. A hippopotamus can stay underwater for 15 minutes. The sperm whale and bottlenose whale can stay underwater the longest: some have been recorded on dives that lasted nearly two hours.

∙ 14y agomarine animals can hold their breath for the same reason as to why humans breathe. it is their natural habitat and they have grown with evolution along time and adapted to their aquatic environments.

∙ 12y agoWhales and human beings are both mammals, and they both need to breathe air, but a whale can stay underwater longer than a human being. This is because whales have bigger lungs (compared to the body) than human beings.

Why can beavers hold there breath so long under water?
Myoglobin enables the marine mammals to be able to hold their breath for extended periods of time underwater. The beaver has been reported to hold its breath underwater for about 15 minutes.
How long can a Harbor Porpoise hold its breath?
The maximum amount of time a harbor porpoise can hold its breath for is unknown. There have been observations of these marine mammals holding their breath for over 5 minutes during dives.
How long can monkeys breath underwater?
No. Monkeys are mammals, so they have lungs, which cannot filter water. They can hold their breath underwater, though.
How long can humpback whale hold breath?
there hold their breath for 97.00 min.For at least 30 mi but suprisingly enough they acually have to breath air to live but can 'hold their breath' for 30 straight minutesThe Humoback whale can stay under water for 15 to 20 minutes max Because they are mammals to and can't hold their breath for very long.
How do mammals breathe underwater?
Mammals typically cannot breathe underwater without assistance, as they require oxygen to survive, and their respiratory systems are adapted for breathing air. However, some mammals, such as whales, dolphins, and seals, have evolved specialized adaptations that allow them to spend extended periods underwater. These adaptations include: Large Oxygen Reserves: Marine mammals have larger lungs and higher concentrations of red blood cells, allowing them to store more oxygen. Efficient Oxygen Utilization: They can conserve oxygen by reducing their heart rate and redirecting blood flow to essential organs. Myoglobin: This protein found in muscles helps store oxygen, allowing marine mammals to remain submerged for longer periods. Blubber: Marine mammals have a layer of insulating blubber that helps them conserve heat and energy while diving. Ability to Close Air Passages: They can close their blowholes or nostrils to prevent water from entering their respiratory system while submerged. Specialized Anatomy: Their respiratory systems are adapted to withstand high pressure and low oxygen levels encountered at depth. Even with these adaptations, marine mammals still need to return to the surface to breathe regularly. They cannot extract oxygen from water as fish do through gills.
How do animals live in the sea?
They move around and eat just like animals on land. Fish use gills to filter water through to breathe, and marine mammals can hold their breath for long periods of time, but have to go to the surface to breathe.
How long can penguins hold there breath?
They can hold there breath over 15 minutes

Do you hold your breath in a ball pit?
No, as long as you stay calm then you don't have to hold your breath.
How long do penguins hold there breath?
they can hold their breath 20 minutes under water
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!!!!!!!!!!!!!!
