Mammals

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.

Yes, homeothermic means warm blooded and all mammals are warm blooded (warm our bodies through food energy). Endothermic animals use the sun or other heat sources (such as reptiles)

Not on land, maybe in water. However, as far as starting time is concerned, a crocodile has a much faster reaction "start" time than a horse does.

There are two, the echidna and the duck billed platypus.

For the typical mammals, the following properties apply:

1) hair on the body

2) endothermic regulation (warm-blooded)

3) milk-producing glands

4) live birth of babies (except egg-laying monotremes)

These animals are all grouped under a single phylum because they all have a vertebrae, or spinal column. They belong to the phylum Chordata taken from the latin chordate.

There are many similarities and differences between fish and cetaceans; some similarities that I can think of right now are that both are aquatic, have fins, and are vertebrates.

All land mammals have four distinct limbs. In bats, the front limbs are wings. In all other land mammals, all four limbs could be called legs. In land mammals that move on two legs, the front legs are sometimes called arms, leaving them with two legs. But this is confusing, because the front limbs could also be called arms. So it is more technically correct to answer the question, "What land mammals can move on two legs?" Humans and the Ground Pangolin are the only land mammals that can walk on two legs for a sustained amount of time. Other primates can walk on two legs as well, but this is not their primary way of moving on land and they cannot sustain it for very long. Macropods (the kangaroo family), kangaroo mice, kangaroo rats, sifakas, sportive lemurs, and the Springhare can hop on land on two legs.

One side to take the deoxygenated blood from the body and send it to the lungs and the other side to receive the oxygenated blood from the pulmonary system and pump it out to the bocy for use.

1. Insectivora

2. Chiroptera

3. Edentata (or Xenarthra)

4. Rodentia

5. Lagomorpha

6. Cetacea

8. Perissodactyla

9. Artiodactyla

10.Proboscidea

11.Primates

That's kind of a big group of animals. All hoofed mammals are ungulates. They're herbivores so probably grass, or leaves, etc.

Mammary (milk-producing) glands are the primary distinction between mammals and other animals.

human,chimp,puppies,kittins,bird,and a bear.

A baby dolphin is called a calf. However, a young dolphin that is 4-6 years old is past the calf stage of life. They are called juveniles.

You're probably referring to the elephant. Many people say that the elephant has four knees (total) on its back legs, but this is wrong. Each of its legs has one knee joint and one wrist joint, like a human's leg or arm.

The greyhound is the fastest dog - with a top speed around 46 mph, but there are several mammals faster than it. Of course the cheetah is considered the fastest - with a top speed around 68 mph (and as much as 75 mph for very short distances), but it can only sustain it's high speed for a short time so at longer distances a greyhound could actually catch up and pass one in a hypothetical race. Other animals that are faster than a greyhound include:

Hare - top speed ~50 mph

Blackbuck antelope - top speed ~50 mph

Lion - top speed ~50 mph

Wildebeest - top speed ~50 mph

Springbok antelope - top speed ~55 mph

Pronghorn - top speed ~55 mph

Ostrich - top speed ~60 mph

Minnows are fish and, like all fish, they are vertebrates because they have a spine and spinal cord, and an internal skeleton. They belong to the Phylum Chordata.

Mammals, birds, fish, reptiles and amphibians are all vertebrates.
