Also all mammals, other than the monotremes , give birth to live young instead of laying eggs. Most mammals also possess specialized teeth and utilize a placenta in the ontogeny . The mammalian brain regulates endothermic and circulatory systems, including a four-chambered heart . Mammals encompass approximately 5,400 species (including humans ), distributed in about 1,200 genera families , and 29 orders though this varies by classification scheme Most mammals belong to the placental group.

Humans are mammals. The word mammal comes from the Latin mamma , meaning breast, because female mammals produce milk to nurse their babies. Nearly all mammals give birth to live young, and all are warm-blooded, maintaining a near-constant body temperature regardless of environmental conditions. They are vertebrates and use lungs to breathe air and are the only animals that grow hair. Mammals probably appeared on Earth some 200 million years ago.

Mammals: Are in the class Mammalia within the subphylum Vertebrata. Are warm-blooded. They have the ability to maintain their body temperature by internal means. The technical word for this is endothermy. Birds are the only other group of animals in the world that can do this. Feed their babies milk Have hair. This unique body covering is made of keratin and grows from special cells located in the skin. Some mammals are hairier than others. Marine mammals such as whales may be virtually hairless. Have a four-chambered heart. This is the most advanced kind of heart. It keeps the arterial (oxygenated) and venous (oxygen-depleted) blood completely separate. Have live birth. The monotremes (platypus and echidnas) are exceptions in that they lay eggs. In marsupials, such as the opossum, the young are born in a very primitive state and then finish their development in an external pouch. Have very specialized and diversified teeth. Again, there are some exceptions (monotremes, baleen whales, e.g.) but the mammals have carried development of teeth farther than any other group of animals.

placental mammal , a group also called Eutheria by scientists. Placental mammals are one of three major groups of living mammals. Marsupials , or Metatheria, form another. This group includes all of the pouched animals, such as oppossums, kangaroos, and Tasmanian devils. The third group, the monotremes , are far less diverse and less well known. They are warm-blooded, have hair, and produce milk just like other mammals, but they lay eggs and do not give live birth like marsupials and placentals. A fourth major group, the Multituberculata , are entirely extinct, though they were once widespread and successful. To explore the world of mammals, click on the group of your choice in the image below. Mammals themselves are part of a larger tetrapod group called the Synapsida . Synapsids make up one of the two largest groups of amniote vertebrates. Note that not all synapsids were mammals. A non-mammalian member of Synapsida is Thrinaxodon . The Thrinaxodon exhibit is of special interest because it uses CAT-scan technology to view the internal structure of a Thrinaxodon skull.

8. What Is A Mammal An introduction to the form and function of mammals, just what are mammals and how do werecognise mammals when we see them? http://www.earthlife.net/mammals/mammal.html

What is a Mammal? Mammals are animals Yes but so are Insects, Reptiles, Spiders, Sponges and Slugs. We need to do better than that. Mammals have a back-bone.Yes but so do Fishes and Frogs and they are not mammals. Mammals are warm-blooded. Yes but so are birds, and birds are not mammals either. So how do we describe a mammal Obviously, what we need in order to define a mammal are some characters, or traits that are possessed by all mammals and are unique to mammals, i.e. they do not occur in fishes and /slugs etc.. Fortunately, scientists have already worked it all out for us. So here are six solid indications that an animal is a mammal Character One The first characteristic that guarantees that an animal is a mammal is that it (if it is female) can produce milk to feed its young. This milk is produced by modified sweat glands called 'mammary' glands. It is from these glands that the whole group takes its name, 'Mammals. Character Two The second test is the possession of hair, something humans often have problems with but which they should respect more. No other animal has hair in the same form as mammals, and all mammals have some hair at least at the beginning of their lives - baby whales and dolphins are born with a moustache. Character Three The lower jaw in mammals is a single bone on either side. In all other vertebrates there are more than one bone on each side of the jaw.

Systematists do not yet agree on the exact number or on how some orders and families are related to others. The Animal Diversity Web generally follows the arrangement used by Wilson and Reeder (2005). Exciting new information, however, coming from phylogenies based on molecular evidence and from new fossils, is changing our understanding of many groups. For example, skunks have been placed in the new family Mephitidae , separate from their traditional place within the Mustelidae (Dragoo and Honeycutt 1997, Flynn et al., 2005). The Animal Diversity Web follows this revised classification. Whales almost certainly arose from within the Artiodactyla (Matthee et al. 2001; Gingerich et al. 2001).

Mammals are vertebrate animals that are endothermic , have hair on their bodies, and produce milk to feed their babies. Many mammals give birth to live young that are small and helpless. Producing milk to feed them allows them to develop more slowly and spend time with the adults as they grow up, learning the skills they need to survive . Regulating their own body temperature and having hair of various thicknesses for protection has also allowed mammals to live in almost every habitat on Earth.

Mammals Mammals have several unique characteristics that differentiate them from other animals. Most mammals have hair, or fur, covering their body. They are also capable of regulating their body temperature. The mammals metabolism controls heat production, and the sweat glands help cool the body. These allow the mammal to maintain a constant body temperature, regardless of the environmental temperature. One other difference is that mammals give birth to fully formed babies, and the female mammals produce milk to feed their young. Most mammals walk on 4 legs, with only the humans walking upright on 2 legs. Aquatic mammals have flippers, or fins, for swimming rather than legs. Common mammals include: primates, such humans and monkeys; marsupials; rodents; whales; dolphins; and, seals. Click on the name or picture of the mammal below for more information.

Animal classes are groups of animals that scientists consider to be alike in some important ways. Mammals are the animal class that people belong to. There are only about 4,000 kinds of mammals. This sounds like a lot, but when you consider there are 21,000 kinds of fish and a whopping 800,000 kinds of insects you’ll realize mammals are a pretty small class! Here are some of the ways that mammals are alike! Mammals are warm blooded. The temperature could be freezing cold or boiling hot, but mammals’ bodies are built to maintain just about the same temperature all the time. Warm blood lets the mammals be very active and live in a wide variety of places. Mammals are everywhere. Polar bears live in very cold areas. Camels live in hot areas. Moles live under the ground. Bats live in caves and fly in the air. Dolphins live in the oceans. Fur and fat help protect mammals who live in the cold. Mammals sweat or pant to release extra heat if they live somewhere toasty.

About Mammals Mammals are warm-blooded, air-breathing, milk-producing vertebrates. The name "mammal" actually refers to the female's mammary glands which provide milk for her young. This characteristic sets off mammals amoung warm-blooded, back-boned animals. Mammals are hairy; young are born alive. Most have varied teeth, for cutting, tearing, or grinding. The mammal's skull is unique; the brain is more complex than in other animals. Being warm-blooded means that a relatively constant blood temperature is maintained irrespective of the outside air or water temperature. This usually means warm-blooded, in fact, since the average blood termperature range for active mammals is 90 to 104 degrees Fahrenheit. Mammals with different diets require different types of teeth. The primitive placental mammalian tooth count was 44, consisting, in each jaw, of: 3 incisors, 1 canine, 4 premolars, and 3 molars on each side. Incisors are for cutting, canines for tearing, premolars and molars are for grinding or shearing. Rodents, which gnaw but do not tear, have lost their canines. Have differentiated teeth means that mammals can chew up their food and prepare it for quick degestions, thus increasing its availability as a source of energy. This makes mammals more active than reptiles, which, after swallowing their prey unchewed, may be sluggish for a week or two till the meal is slowly digested.
