Title: Mammals

Mammals

Characteristics of Mammals
  • Most mammals have hair or fur covering their
    bodies.
  • Mammals are capable of regulating their own body
    temperature. Metabolism controls heat production
    and sweat glands cool the body.
  • Mammals give birth to fully formed babies.
  • Females are able to produce milk to feed their
    young.

Locomotion
  • Most mammals walk on four legs, with the only
    exception of humans, who walk upright on two
    legs.
  • Aquatic mammals have flippers or fins for
    swimming instead of legs.

4
Types of Mammals
  • Mammals are divided into three subclasses based
    upon their method of reproduction.
  • Placental Mammals The young develops in
    mothers uterus. Examples Giraffe, Elephant,
    Bat, etc.
  • Marsupials The young develop in mothers pouch.
    Examples Kangaroo, Koala.
  • Monotremes The mother has fur and produces
    milk, but lays eggs. Examples Duck-billed
    Platypus, Echidna.

Placental Mammals
  • Giraffe
  • Located in Africa, giraffes have an average
    lifespan of 20 years.
  • Giraffes are the tallest animals and have the
    highest blood pressure of any animal.

6
Elephant
  • There are two species of elephant African and
    Asian
  • Elephants have an average lifespan of 60-80
    years.
  • Elephants keep cool by throwing dirt on their
    backs and by fanning their ears.

Vampire Bat
  • Bats are the only mammal that can fly and they
    make up one quarter of all mammal species!
  • Vampire bats live in South America and have an
    average lifespan of 5-10 years
  • They survive by drinking blood from other animals.

8
Marsupials
  • Kangaroo
  • There are over 60 species of kangaroos.
  • Kangaroos are marsupials who live in Australia
    and have an average lifespan of 7-15 years.
  • Their young are born after 5 weeks, whereby they
    crawl into the pouch for further development
  • Male kangaroos box with each other to show
    dominance.

9
Koala
  • Koalas are marsupials from Australia who have an
    average lifespan of 15-20 years.
  • Koalas only eat eucalyptus leaves, and do not
    drink water (the name Koala means no drink)
  • Koalas sleep between 16-22 hours a day in order
    to digest the eucalyptus.

Monotremes
  • Duck-billed Platypus
  • The duck-billed platypus lives in Australia and
    has an average life span of 10 years.
  • The male duck-billed platypus has a poisonous
    spur on his hind legs.
  • Platypuses live in burrows and find food in
    rivers.

11
Echidna
  • The echidna, also known as a spiny anteater,
    lives in Australia.
  • Echidnas are nocturnal animals, and are currently
    endangered.
  • Echidnas have spurs on their hind legs that
    produced venom at one point in their evolutionary
    history.
