Mammals

Mammals with thick fur, a layer of fat for insulation, and the ability to conserve body heat, such as polar bears or arctic foxes, are more likely to survive in sub-zero climates. Their evolutionary adaptations help them withstand extreme cold temperatures.

The largest land mammal in the Arctic is the muskox, which can weigh up to 900 pounds and stand over 4 feet tall at the shoulder. Muskoxen have a thick coat that helps them withstand the harsh Arctic conditions and are known for their distinctive curved horns.

Similarities: Both mammals and reptiles are vertebrates, breathe air, and are warm-blooded.

Differences: Mammals give live birth, have hair or fur, and produce milk to feed their young, while reptiles lay eggs, have scales, and do not produce milk.

There are approximately 462 species of mammals in North America. This includes a diverse range of animals such as bears, deer, squirrels, and bats, among others.

First of all, most mammals have fur rather than hair.

Both fur and hair primarily provide warmth. Fur and hair, however, also provide distinctive markings that can be involved in mating, aid in touch-sense input, and provide protection from the sun.

In addition, some more aquatic mammals (such as seals and otters) have a high oil content in their coats, which aids in buoyancy in the water.

I'm almost certain that fur and hair have other uses, especially if you add whiskers into the larger hair-and-fur discussion.

One example of a mammal that sleeps hanging upside down is the bat. Bats are able to hang upside down due to special tendons in their feet that lock into place when they roost. This position allows them to take off quickly if needed while providing safety from predators.

Other animals include; amphibians, reptiles, birds, fish, insects, worms, molluscs and many more.

Having internal lungs allows mammals to efficiently exchange gases with a large surface area, maximizing oxygen uptake from the air. It also helps protect the lungs from drying out and injuries. Additionally, internal lungs provide a better control over the breathing process, enabling mammals to regulate their respiration rate as needed.

Humans evolved to have buttocks (cheeks) as part of their anatomy for various reasons including providing cushioning for sitting, aiding in balance and movement, and facilitating heat dissipation. Additionally, having well-developed gluteal muscles is important for posture and overall body strength.

Lipids (fats) are heavier, more calorie dense and are not water soluble...which makes them a better candidate for storage in an animal system...fat is also a great insulator that helps maintain body temperature. Fat is also a better, more flexible for animals which need to move.

Plants convert and store carbohydrates in the form of starch and cellulose. Cellulose is structural, not generally flexible...

A Yorkshire Terrier is a heterotroph. Heterotrophs are organisms that cannot produce their own food and must consume other organisms to obtain nutrients for energy.

Depends on how you count. A blue whale will probably eat the most in weight during a day, while something like a shrew will probably eat the most compared to its body weight.

The big cats can eat huge amounts compared to their body weight too, but then they'll spend 3-4 days sleeping it off, bringing their average down.

The legs of a cat and fins of a whale are analogous structures because they have different evolutionary origins but serve a similar function in terms of movement. Homologous structures would be when two species share a common ancestor and have similar structures with different functions.

The gestation periods for mammals differs greatly. In general it appears to be very short in small mammals, (some shrews and mice are only a few days) while increasing in length as the mammal increases in size. Elephants, hippos, bears whales and other large mammals have gestation periods lasting 9 to 18 months.

Vampire bats are nocturnal because their prey, primarily livestock, are usually sleeping at night, making them easier to feed on without detection. Additionally, nighttime offers better cover and protection from predators for vampire bats while they hunt.

No, all mammals need lungs to breathe, as lungs are the primary organs responsible for gas exchange. Mammals have evolved to depend on lungs for respiration due to their efficient exchange of oxygen and carbon dioxide with the blood.

No, jackals are mammals that bear live young.

Many animals are born without fur. Among them are rats, mice, aardvarks, rabbits, wombats, squirrels, groundhogs, raccoons, birds, and bats.

And humans! Even though our hair is vestigial rather than a full coat.

Nocturnal animals are animals that are active at night rather than the day. At night, they forage or hunt for food and perform other activities, which depend on the species. During the day they sleep.

Yes, many mammals can eat seeds as a part of their diet. Some mammals, such as rodents like squirrels and chipmunks, have specialized adaptations for consuming seeds. However, not all mammal species can digest seeds effectively due to their digestive systems.

This depends entirely on whether the mammal is a carnivore (meat eater), herbivore (plant eater), or omnivore (eating just about anything). There are also the insectivores (insect eaters) and frugivores (fruit eaters).
Mammals live in a variety of habitats so they eat a variety of food. Some like horses and cattle are herbivores and eat grass and vegetation. Some like lions, tigers are carnivores and eat flesh of other animals. Some like whales and dolphins live in the sea and eat fish and shrimps etc. Some like humans are omnivores and eat meat and vegetation.

While birds are vertebrates, they are not mammals. Mammals have a series of general characteristics that include (with exceptions) birthing live young, having hair or fur as an outer covering, and producing milk to feed their young.

No, warblers eat small insects and spiders so they are insectivores. A herbivore eats plants.

Mother mammals make milk for their offspring.

A lizard is a Squamate Reptiles, that has almost 5,000 different species . They are seen in around oceanic island.
