Types of Mammals
Transcript of Types of Mammals
Marsupials have short pregnancies. They give birth to tiny, helpless young. For example, a newborn kangaroo is only about 1 inch (2.5 centimeters) long. The newborn immediately crawls into a pouch on the mother's body. There, it latches onto its mother's nipple and feeds on milk. The young marsupial typically remains in the pouch for several weeks or months. It only leaves the pouch when it has grown enough to move about on its own. Some marsupials do not develop in a pouch. Instead, they cling to their mother's body. Marsupials make up one of three major groups of mammals. The largest group is made up of Placental Mammals.
What is an Animal?
Heterotropic: An organism that can't make its own food
Eukaryotic: Having cells with nucleus's
Multi-cellular: Having more than one cell
An animal is an living organism.
Traits of Chordates
All chordates have a backbone.

What is a Mammal?
a warm-blooded vertebrate, which is an animal with a backbone, animal of a class that has the charecteristics of hair or fur, females produce milk for their young, and, for the most part, give birth to their young. There is also three different groups of mammals. Monotremes, Marsupials, and the Placentals. Monotremes give birth to leathery eggs and example would be a platypus. A Marsupial gives pirth to imature young and nurse them in their pouches (kangaroo). Placental animals don't give birth until they are full grown (humans).
What is an animal?
2.True or False: Marsupials make up one of the three major groups of animals?
3.Marsupials have_____ pregnacies.
4.A new born kangaroo is only ____ long at birth
5.The largest group is made up Plancental ___-
An heterotroph animal is an animal that cannot make their own food, so they hunt
An animal that is multicellular is an animal with many different cells in their body.
A eukaryotic animal is an animal that has a nucleaus (which is a brain to your cell) in their cells.
1. All mammals give birth to their young. T or F

The Seven Levels of Classification
A placental mammal is a mammal with a placenta. All mammals except monotremes and marsupials have a placenta. A placenta is flattened circular organ in the uterus of pregnant mammals. An umbillical cord is connected to the placenta and, the umbillical cord to the baby. The placenta gives the baby the nourishment it needs to survive before it is born. Examples of placental mammals would be horses, elephants, cats, dogs, and hamsters; even though there are many more. Ane even though sharks aren't mammals they are placental!
Monotremes are a primitive mammal that lay large yolky eggs and have a common opening for the urogenital and digestive systems. Monotremes only live in Australia and New Guinea. The only monotreme species there are in the world are platypuses and echidnas.
Marsupials are mammals of an order whose members are born incomplete and not developed and are normally carried in a pouch on the mother's belly. Marsupials are found mainly in Australia and New Guinea, although three families, live in America. Some examples of marsupials are kangaroos, opposums, wallabies, koalas, wombats, tasmanian devils, and gliders.
It is in the chordata group.
They are in one of the three
major groups. Marupials and Montemes
The seven levels of classification is a group that helps determine which group each animal should be in. An example would be like if you had a group of school supplies and you wanted to serperate them into groups. Say you had some erasers, pencils, pens, and a pencil sharpener. You could group the writing supplies (pencil and pen) together and the untencils (eraser and pencil sharpener) together. Which would be an example of clasification. You also need to know binomial nomenclature, to be able to classify animals. Bimomial nomenclature is the scientific name of an object. It can also help you classify an object into groups.
Animals with a backbone.
1. A umbilical cord is connected to the placenta.
2.The umblical cord is clamped off after birth.
3. Some parents chose to save the umbilical cord as transplant alternative to ____ ______.
4. The umbilical cord is a ________ structure.
5. its main function is to carry nourishment and oxygen from the ________ to the fetus.
D. Blood Vessels
A lion is a mammal which is classified in the placental mammal group. It has hair and fur and is a carnivore.

Words to look out for:
Before you buy an animal think about what they'll need and how they survive. Ask question when you're about to buy and before you but. do some research on the animal or animals you are interested in. So that you can you get a better understanding of the animal and how that animal live.
Marsupials are a type of mammal
