There are three groups of mammals; egg-laying mammals ,pouched mammals and placental mammals.
These three types of mammals
are different for one main reason: reproductive methods. The egg-laying mammals lay eggs. The pouched
mammals give birth to underdeveloped offspring. The offspring then spends time in the mother\'s pouch,
and mature. The placental mammals keep their offspring inside them then give birth to a fully developed
2. The anteaters and spiny ant eaters were two separate kinds of mammals. the Spiny anteater lays eggs to
reproduce, the anteater does not.
3. Two pouched mammals are Kangaroos and Koalas. Their young develop in pouches.
4. Mammary Glands are glands on the female mammal. They produce milk for the offspring to drink.
5. There are ten types of placental mammals. Here were their names and characteristics.
1. Toothless No teeth
2. Water dwelling Live in water
3. Trunk Nosed Have trunks as noses
4. Rodent like Similar to rodents
5. Insect Eating Insects as food source
6. Flying Flying
7 Primates Ape like
8 Gnawing Eat by Gnawing
9 Flesh Eating Carnivorous
10 Even hooved Feet were hooves with even sides.
6. Whales were considered mammals for three reasons. First of all, they bear live young. Secondly they
must surface for air. Lastly, they feed their young with mammary glands.
7. Sharp teeth help predators to devour their prey.
8. Primates were considered the smartest animals because they use their
The Naked ApeThe Naked Ape In The Naked Ape, Desmond Morris provides an alternative explanation of the causative factors underlying various human behavior patterns and societal and cultural activities. He develops his theme around such human activities as feeding, grooming, sleeping, fighting, mating and care of the young. He compares human traits and behaviors with those exhibited by animals, mainly the primates, in like activities. His point is that understanding the evolutionary source of many behaviors c
The History of DinosaursThe History of Dinosaurs The dinosaurs were reptiles that appeared about 230 million years ago. It\'s believed that they had scaly skin and some ate plants and others ate meat. Scientists don\'t know whether or not the dinosaurs were cold blooded, but they think the smaller ones were warm blooded, and the large ones were cold-blooded. In this report you\'ll learn about the earliest dinosaurs, the kinds of dinosaurs, and how the dinosaurs died. There are two main groups of the earliest dinosaurs:
The Ice AgeThe Ice Age Twenty thousand years ago during the time of the last ice age period, many colossal mammals roamed North America. They survived during the times when much of the earth was covered by immense large bodies of ice that buried forests, fields, and mountains, but rapidly became extinct after the ice began to retreat and melt. Since then the human race has introduced many different theories to explain the extinction of these large mammals. One theory stands above all and explains the truth
Creationism vs. EvolutionCreationism vs. Evolution In my short life on this planet I have come to question things that many take upon blind faith. We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of an unfathomable scale than to question the existence of a supposed

The Digestive SystemsThe Digestive Systems The digestive systems works on nutrients taken from the environment, breaking them down into simpler products, and then absorbing the products together with water and salts so they can be used in metabolism. The individuals of all species contain many different protiens or carbohydrates in the cell walls of bacteria, chitin in the external skeletons of arthropods, and so on and foreign proteins or carbohydrates are rarely incorporated unchanged. They are usually first broke
Bald Eagles and Golden EaglesBald Eagles and Golden Eagles Eagle is the common name for a number of diurnal birds of prey, some of which are the largest members of their family which also includes kites, hawks, buzzards, and certain vultures. The name eagle is somewhat loosely applied, as several of the groups are not particularly closely related to one another, and some birds called hawks are larger than some called eagles. The Bald Eagle (Haliaeetus Leucocephalus) and the Golden Eagle (Aquila Chrysaetos) are two eagles th
Genetic Engineering, history and futureGenetic Engineering, history and future Altering the Face of Science Science is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from analytical engine, to calculator, to computer. But science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history will science be able to so deeply af

Their sizes range from about as big as a mouse to as large as a cat. They have a roundish head with a pointed muzzle and large eyes. Their fur is wooly and their legs are longer than their arms. They are nocturnal animals, feasting on mostly plants, s

MARINE BIOLOGISTSMARINE BIOLOGISTS Perhaps one of the most important administrations in the world is the Nation Oceanic and Atmospheric Administration, more commonly referred to as the NOAA. It was established in 1970. There are 400 officers in the program and over 12,000 employees. This organization helps the career of Marine Biology and promotes its well being. Welcome to the wonderful world of Marine Biology. Marine Biology starts when there is pollution in the water and then they take samples of the water an
THE PEREGRINE FALCONTHE PEREGRINE FALCON Speech topic: The Peregrine Falcon Specific purpose: to inform my audience about the size, appearance, range, hunting and eating habits, and other characteristics. INTRODUCTION ANECDOTE -- One afternoon an American pilot stationed in Germany was in a free dive with his jet, engines on but not propelling him downward faster than gravity would allow. He looked out to his side and saw a small bird in a dive nearby. He was surprised to see a bird this close to the plane, but not
The Spectacled BearThe Spectacled Bear The Spectacled Bear, or Tremarctos Ornatus, is an endangered species. This rare bear can only be found in a few elusive spots in the world. Many endangered species all over the world dont deserve the respect and care that they need. That is why many endangered species often become extinct or remain on the endangered species list for the remainder of their survival on Earth. Today, as more species become endangered, more people become involved in their care. Many things are b
I am going to compare and contrast the similaritieI am going to compare and contrast the similarities and differences between dogs and cats. The similarities are innumerable, yet this holds true with the differences as well. First, we shall discuss the similarities that these two creatures share. One of the most obvious similarities between these two animals is that they both have hair. When a creature has hair, it belongs to the mammal kingdom. This means that they give birth to their young. They also drink milk when they are babies. Another s
LithosphereLithosphere Notes on the lithosphere- (rock sphere) Upper most part is crust of earth. Compiled of rocks of outer crust. Outermost shell. Upper part- rocks we see at and near the earths surface. Crust is 5 to 10 km thick under most oceans and 24 to 60 km thick under the continents. The lithosphere under the crust is solid, dense material. (more dense than surface materials). Lithosphere 100-200 km. Notes on the aesthenosphere- zone beneath the lithosphere. Thick like tar. Weak because of high te
