Mammals

kangaroo

Excluding a population of dwarf woolly mammoths on Wrangel Island (which lasted until 3,700 years ago), woolly mammoths became extinct 10,000 years ago.

The species of mammoth native to North America was the Columbian mammoth. One skeleton of a Columbian mammoth has been dated to being less than 8,000 years old.

an animal that has fur and that swims is a polar bear.

The more general brain development of the animal behind the less time sleeping they need, because the brain is the evolution of animals from the last one of the senior organ, the human brain is the youngest, and therefore we are not very perfect, and need the regular rest, but like a rat, it just need little sleep. Also, the fish is sleeping, sleeping or not is not muchrelated to closing eyes or not, and some fish can swim while sleeping, such as tuna. In addition, the nutritional intake in relation to the physical consumption of small animals need to sleep, in order to slow down the metabolism.

No. Individual bees are insects in the order Hymenoptera.

The superorganism of a bee nest shares many of the characteristics of a mammal:

Mammals produce few offspring: just like the bee nest.

Mammals produce milk for their young: Bees produce milk (royal Jelly) for their young.

Mammals have a uterus that allows their young to develop away from the external factors such as weather and temperature. Bee nests have a social uterus to maintain a controlled and protective environment for their young.

Mammals have a body temperature of approximately 36 degrees: A bee nest maintains a temperature of around 35 degrees.

Mammals have the ability to learn: Bee nests have the ability to learn and adapt to their environment.

(For a more detailed analysis of bees as an superorganism read 'The Buzz about Bees' by Jurgan Tautz available from many internet retailers.)

Neither. Possums, or at least true possums, which are found in Australia, are marsupials.

about 4 to 8 babies a month because it takes 6 week to have babies

actually it takes 21 days for a mouse to have babies and the litter size can range anywhere from 2 to 12 babies a litter so if the litter ranges in 8 babies a litter you could have 139 babies a year

By mass, the smallest mammal in the world is the Etruscan Shrew, Suncus Etruscus, which weighs only about 2 grams. By length/size, the smallest mammal in the world is Kitti's Hog-Nosed Bat, Craseonycteris Thonglongyai, which is only 29-33 millimeters long.

Woolly mammoths were adapted to living in freezing conditions towards the northern most area of earth, for example where Siberia now is. As the conditions have remained freezing since the ice age, mammoths that have been buried under snow since they were dead have not decomposed. This is because as the stable freezing cold for millions of years slows down the animation of bacteria. They too are frozen in the process, and decomposition occurs because bacteria in the internal organs of the animal, and in the atmosphere multiply without the control of an immune system and devour the body leaving a soup like waste product. And of course flies, and other such life form that feed on carcasses are unable to get to it because it is buried deep in ice. This, combined with having the effect of bacteria eliminated from the remains leaves an almost perfectly preserved mummified mammoth.

Sorry but since the list of mammals is extensive and the list of birds is a matter of pages and the listing of fish would also extend for pages while insects alone might be more than a few volumes you are respectfully denied a quick and easy answer.

Yes they are because you get food from them even if you don't know it and mostly at the farms you get meat and meat is from animals.

Like you drink milk out of a cow and you get cloth from a sheep.

That'd be hard to say since every little bug counts as wildlife. I imagine it'd be California as it stretches vertically making it have numerous eco-systems(desert, mountains, forest, ocean, etc) thus more kinds of wildlife.

Solenodons, short-tailed shrews, the Eurasian Water Shrew, and the European Mole inject venom into prey by biting it; the venom is transferred through teeth. Male platypuses inject venom through spurs on their back legs; female platypuses and both sexes of echidnas also have these spurs, but they cannot inject venom.

They have hair, a skeleton, 4 limbs, circulatory system w/4 chambered heart, and are endothermic. ---- There are five basic features which characterise mammals: * they are vertebrates * they have fur, skin or hair * they are warm-blooded * they breathe through lungs (not gills) * they bear live young (with the exception of the two monotreme types, which lay eggs) and the young feed on mothers' milk

stop being gross loser

They can be both. Many reptiles, particularly snakes, help keep populations of rodents and other animals under control, and so are an indispensable asset to farmers. Without snakes many places would face famine. Crocodiles and alligators help clean up carrion from lakes and rivers and help keep their prey populations under control as well. At the same time they can be harmful. Venomous snakes kill thousands of people every year and injure even more as they bite in self-defense. Some large constrictors kill in self defense as well. Crocodilians sometimes attack and kill people who enter their territory and, in some instances, eat them. There have also been a few cases of people being eaten by large snakes and komodo dragons.

it is a lion that is the largest

This is wrong. The Clouded Leopard has the longest canines of any wild cat.

Yes, reptiles are NOT mammals. Reptiles are exothermic vertebrates (coldblooded), have no fur, lay eggs and do not lactate. Mammals are endothermic vertebrates (warmblooded), have fur/hair, give birth to live young and lactate.

Mammals have blue blood (lack of oxygen), but when exposed to oxygen, it turns red

Hope this helped! :)

The largest mammal in the world is the blue whale. They have been known to be over 100 feet long and to weigh as much as 200 tons. They are not only the largest living animals, they are the largest animal that is known to have ever existed.

Eagles are large birds of prey, while bats are mammals that fly, most species are tiny creatures, although fruit bats can be quite large, but not eagle size,

I don't think there is one. There is a type of Waterbuck (a type of Antelope) that is called the Lechwe, maybe that is what you are thinking of?

A platypus is sometimes regarded as having a bill like a duck, but in fact its bill does not look like a duck's bill, being flatter and much broader, and made of a totally different substance; nor does it serve the same function as a duck's bill, having very unique properties such as electroreception.

Crocodiles and dinosaurs are both classified as types of Archosaur but they are on different branches and therefore different groups.

The biggest, most obvious difference is that crocodiles walk on sprawled limbs that stick out the side of the body whereas dinosaurs walk on erect limbs held below the body.

In actuality very few dinosaurs look anything like crocodiles. Some dinosaurs are bipedal, some fly (birds) even most the quadraped dinosaurs dont look like Crocodiles.

The most crocodile looking dinosaurs are probably the herbivorous ankylosaurs. These are covered in scales, armor and have a low profile. But even these don't really look like crocodiles.

Not all dinosaurs are covered in scales. There are some groups which are covered in feathers. All crocodiles are covered in scales.

These days mesozoic dinosaurs are generally thought to be warm blooded. Modern day dinosaurs, the birds, are also warm blooded whereas crocodiles are cold blooded.

Rather than use mesozoic dinosaurs, which are sadly extinct, why not use modern day dinosaurs and ask the question: What is the difference between birds and crocodiles? Some of the the differences should become more aparent.
