How do mammals breathe underwater?
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).
What is a mammal that carries their young in pouches?
A kangaroo is an example of a mammal that carries their young in a pouch. The joey, or baby kangaroo, develops inside the mother's pouch after being born extremely premature.

What is the scientific name for egg laying mammals?
Egg laying mammals are monotremes. They belong to the order monotremata.
Yes, a cat is a placental mammal. Placental mammals are a group of animals that give birth to live young, nourished through a placenta during gestation. Cats fall into this category as they exhibit this reproductive mechanism.
When did humans and mammals appear on earth?
The first true mammals appeared on Earth around 200 million years ago, in the late Triassic period. However, these mammals would remain small and relatively insignificant due to the dominance of the dinosaurs. Only when they died out 65 million years ago did mammals grow and diversify to become the ones we see today. The first modern humans (Homo sapiens sapiens) evolved around 200,000 years ago.
That is correct. Mammals are characterized by features such as having body hair, giving birth to live young, and producing milk to feed their offspring. Humans share these characteristics with other mammals.
Yes, a human being is a mammal. Mammals are a group of vertebrate animals that have mammary glands to nurse their young, hair or fur, and typically give birth to live young. Humans possess all these characteristics, making them mammals.
What is the slowest mammal on earth?
I'm sure its a three-toed sloth. They only come down from a tree once a week. Scientists who study sloths are always falling asleep - I'm not joking! Imagine watching a furry green thing do nothing for hours on end? The first thing a scientist who first saw the sloth said was: "I have never seen an uglier or more useless creature." But still their faces are quite cute I have to admit.
What kind of tools do mammalogist use?
Mammalogists use various tools such as binoculars, camera traps, GPS devices, radio telemetry equipment, and mammal identification guides to study and track mammals in their natural habitats. They may also use microscopes, scales, and measuring instruments for specimen analysis in a lab setting.
Yes, humans are mammals, because we have warm blood, we give birth to live young, and females produce milk to nurse their young.
Yes.
They share the same characteristics that every mammal does:
All mammals are warm blooded.
Most young are born alive.
They have hair or fur on their bodies.
Every mammal is a vertebrate.
All mammals have lungs to breathe air.
Mammals feed milk to their babies.
Yes.
They share the same characteristics that every mammal does:
An organisation with a culture of cybersecurity does not create an additional layer of security. Instead, it weaves it into the very fabric of the organisation. Let us now see how that can be accomplished.
Why fish use less energy in excreting nitrogeneous wastes than mammals and birds?
Yes, they do. Fish do not need to create urea or uric acid in order to excrete their wastes because they live in water, they can simply excrete the waste out of their gills, which requires less energy than having to create uric acid etc.
Marsupials give birth to immature live young that continue to develop within the mother's pouch?
Marsupials do give birth to immature live young that continue to develop within the mother's pouch. After it climbs up the mother's belly and gets in the pouch it grabs on to one of the teats. After several weeks, the young marsupial starts coming out more and more. It leaves the pouch when it is about 7 to 10 months old.
What is North Dakota's state mammal?
The official state bird of North Dakota is the Western Meadowlark, adopted by state legislation in 1947.
Whales and dolphins spend all their life in water. Why are they classified as mammals?
They both make milk for their young (and at some point in their life they have hair).
Why are mammals different from fishes?
Yes, they are. Fish cannot be removed out of water without dieing, but mammals can be in water and land, and mammals have more organs than fish, but fish are the only ones with a Swim bladder. A Swim Bladder helps the fish find density in water to float and swim.
