FC: The Life of Mammals By: Asia McGauley and Ravi Parashar
1: Mammals also have certain shaped teeth to help them adapt to their animal diets | Mammals are endothermic vertebrates with four chambered hearts. | Mammals have fur and hair to keep them warm in cold temperatures and cool them down in warm temperatures | Classification Page | Mammals are classified in the class of Mammalia. Which consist of about 6,000 or more species
2: Biomes by Class | Many mammals live in different types of habitats or biomes. Mammals live in all the biomes. | Animal Biomes -Desert Biomes(Camels) -Grassland Biomes( Lions) -Deciduous Forest Biomes( Black Bears) -Tundra Biomes( Polar Bears) -Boreal Forest Biomes(Porcupine) -Fresh Water Biomes(Brown Bear) - Marine Biomes( Whales and Dolphins) | Biome- A group of ecosystems with similar climates and organisms.
3: The way mammals reproduce | Mammals have Internal Fertilization | Most mammals babies/young are developed in their mother's stomach. Although some mammals do lay eggs. | Mammals young are fed milk that is produced by their mother in the Mammary Glands. | Many mammals reproduction method is internal.
4: Mammal Behaviors | Sometimes mammals act a certain way because they need to find mates. Like lions fighting for a mate. | Mammals can also act in certain ways because they are scared or they are trying to express some type of emotion. | Some mammals are very territorial, such as lions. They pee on a bush or tree to show that they have been there.
5: Mammal Feeding Habits | Mammals have many different diets. Some are carnivorous such as lions and tigers. | Others are herbivorous and only eat plants, like giraffes. | Mammals have specialized teeth based on their diet.
6: Type of Symmetry | Mammals have bilateral symmetry. Bilateral symmetry helps them with speed and balance. | Many mammals such as tigers use the bilateral symmetry in day to day life. They hunt for food and have great balance thanks to bilateral symmetry.
7: Characteristics by Order | Mammals have fur or hair at some point in their lives. They usually give birth to live young except in the case of platypuses. Mammals also feed their young with milk.
8: Food Web | Food webs show which animals eats which animal and which one is on the top of the food web, which means they have no predators.
9: When did Mammals first appear | Mammals first appeared 270 million years ago. | The first mammal like creature looked much like a mouse that's habitat was surrounded by dinosaurs. | The earliest mammals were nocturnal and or very active at night. | Most mammals are specialized to live on land or either water.
10: Fur and Hair | The thick fur helps to provide insulation that keeps body heat from escaping | The fur and hair help to keep the animals warm in cold temperature | The hairs on the mammals are made of dead cells | Animals that have a thicker coat of fur live in colder regions then animals in warmer regions.
11: Mammal Teeth | The teeth help to digest the food so that the animals can eat them better and quicker | Shapes, Size and Hardness help the mammal better it's diet | Mammals have 4 different types of teeth : Incisors, Canines, Premolars, and Molars | For mammals to keep up their energy they have to have great teeth to eat
12: How do they obtain oxygen? | All mammals like humans breath through their lungs. | All mammals breath in and out because of a rib muscle and a larger muscle called the Diaphragm | Oxygen dissolves in the lungs and moves to the bloodstream. | Mammals have a four chambered heart and a two-loop circulatory
13: Nervous System and Senses | Mammals have a very complicated nervous system, far more complicated than insects. Because of mammal's nervous systems they can complete whatever the wish to do with ease. Mammals have a very large brain in comparison to other animals.
14: Movement | Thanks to their complicated nervous systems mammals can complete actions very smoothly. Mammals can move with great ease because of the complexity of their nervous system and their skeletal system.
15: Monotremes | Monotremes are specials kinds of mammals that actually lay eggs instead of giving live birth. These include the duck-billed platypus and the spiny anteater.
16: Marsupials | Marsupials are types of mammals that give live birth, but in the early stage of development, they stay in their mother's pouch.
17: Placental Mammals | A placental mammals develops inside its mothers body until its body systems can function properly. One mammal in this group is the biggest land animal, the elephant.
