What Is A Mammal? • Mammals are animals that have hair, are warm-blooded, and nourish their young with milk. • Some modern-day mammals include people, apes, dogs, mice, elephants, pandas, and many more.
Types Of Mammals • Monotremes: are primitive egg-laying mammals. • Marsupials: their young are born in an extremely immature state. • Placental mammals: their young are born at an advanced state.
Monotremes • Monotremes are the most primitive mammals. These mammals lay eggs, after the babies hatch, the mothers nourish their young with milk. Today, monotremes only live in Australia and New Guinea.
Types of Monotremes • There are three species of monotremes: • The duck-billed platypus and two spiny anteaters. • This is a picture of a duck-billed platypus
Marsupials • Marsupials are pouched mammals whose babies are born in a very undeveloped state. The young attach themselves to their mother. Many marsupials have a pouch that encloses the young. • Marsupials evolved about 100 to 75 million years ago, during the time of the dinosaurs.
Types of Marsupials • The biggest is the human sized red kangaroo. • The smallest is the pilbara, it would fit in a persons hand. • Kangaroo, opossum, Tasmanian devil, and koala the most common. • The only marsupial in North America is the Virginia opossum. • Pictured is a kangaroo.
Placental Mammals • Placental mammals are advanced mammals whose young are born at an advanced stage. • Before birth the young are nourished through a placenta. The placenta is attached to the mother’s uterus and it delivers oxygen and nutrients to the young. • Most mammals are placental mammals.
Types of Placental Mammals • There are almost 4,000 known species of placental mammals. • The most common: people, cats, dogs, and horses.
Mammal Diets • Mammals have to eat a lot to maintain their high body temperature. Diets vary from mammal to mammal. As with most animal groups, there are more herbivores (plant-eaters) than there are carnivores (meat-eaters).
The Different Types of Diets • There are four types of diets that mammals can have. They can be: • Herbivores • Carnivores • Omnivores • Insectivores
Herbivores • Herbivores are plant eaters. • Some herbivores include: beavers, cows, horses, pandas, sloths, and others. • Pictured are panda bears.
Carnivores Baby Dolphin • Carnivores are meat eaters. • Some carnivores include: whales and dolphins, dogs, tigers, lions, and others.
Omnivores Grizzly Bear • Omnivores eat both plants and meat. • Some omnivores include: people, some bears, and others.
Insectivores Aardvark • Insectivores eat insects. • Some insectivores include: aardvarks, anteaters, and others.
Venomous Mammals • Only a few mammals are venomous. • These mammals include: male duckbilled platypus, several species of shrews, and the Solenodon (a small insectivore). Haitain Solenodon
Mammal Extremes • Here are some fun mammal facts. • We are going find out what the fastest, slowest and biggest mammals are. • We will also learn what the smallest, loudest and smelliest mammals are. • Along with some other cool facts.
The Fastest Mammal • The fastest mammal (also the fastest land animal) it the Cheetah. • The cheetah runs between 60 and 70 miles per hour.
The Slowest Mammal • The slowest mammal is the sloth. • The sloth moves less than 1 mile per hour.
The Biggest Mammal • The biggest mammal also known as the biggest animal that ever lived on Earth is the blue whale. • The biggest land mammal is the African Elephant. African Elephants
The Tallest Mammal • The tallest mammal is the giraffe.
The Smallest Mammals Pygmy Shrew • The smallest mammal is the pygmy shrew and the bumblebee bat. • The pygmy shrew weighs between 1.2 and 2.7 grams. • The bumblebee bat weighs about 2 grams.
The Loudest Mammal • The loudest mammal is the blue whale. • The second loudest is the howler monkey. • Pictured is a Black Howler Monkey.
The Smelliest Mammal • The smelliest mammal is the striped skunk.
The Fattest Mammal Ringed Seal Pup • The blue whale has the thickest layer of blubber, but the ringed seal pups have the greatest percentage of fat (about 50%).
More Mammal Facts • There are about 5,000 species of living mammals • You have learned that mammals are divided into three subclasses: Monotremes, Marsupials, and Placental mammals. • Mammals unlike other animals have body hair, three middle ear bones, and nourish their young with milk that females produce.
What Did You Learn? • Hopefully you have learned a lot more about mammal. • I also hope that you found the facts interesting, like the biggest and smelliest mammal. • Do you now know what creature in the picture is not a mammal?
