The state mammal of Michigan is the white-tailed deer (Odocoileus virginianus).

The mammal group with the highest population is the mouse. With an estimated 30 per every human on earth, that means there are approximately 210 billion mice on the planet.

The single mammal species with the highest population would be Humans. Cows number approximately 1.3 billion. Dogs number 500 million, cats number 300 million. In short, the animals whose specie has the highest numbers are the ones with the most importance to humans.

Outside of rodents, chickens have the largest population with 24 Billion.

Some people would say humans, but there are only about six billion of us. I would suggest that it would be either an animal that is useful to us (ie. sheep, cattle) or a rodent. My best guess would be the rat or mouse.

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.

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.

Ruminants, such as cows, sheep, goats, and deer, have hooves and chew cud. Cud is partially digested food that is regurgitated and rechewed to aid in better digestion.

The scientific name for egg-laying mammals is monotremes. These unique mammals include the platypus and echidnas, which lay eggs instead of giving birth to live young.

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.

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.

The slowest mammal on Earth is the three-toed sloth, which has a top speed of around 0.24 km/h (0.15 mph). These slow-moving animals spend most of their time hanging upside down in trees and move slowly to conserve energy.

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 they belong to the class Mammalia, which is characterized by features such as giving birth to live young, having mammary glands to nurse their offspring, and having hair or fur on their bodies.

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.

Dolphins and Whales

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.

The Etruscan Shrew, Suncus Etruscus.

When agitated, they tend to make a huffing sound, almost as if a cat would.

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.

The official state bird of North Dakota is the Western Meadowlark, adopted by state legislation in 1947.
