1adaptation in animals the idea that certain
animals have developed features which help them
survive in their environment

3Elephants
- Elephant's bodies are well adapted for survival
in the rugged conditions of Africa. These special
adaptations include
4Elephants
- The TrunkThe elephant's trunk does so much more
than smell. This "hose nose" is also used for
drinking (actually blowing water into the mouth),
communication, feeding, chemo-communication,
offense/defense, touching, lifting, greeting,
caressing, throwing dust, and just about any
other activity an elephant is involved in.
5Elephants
6Elephants
- EarsIn the hot African climate, keeping cool is
a constant challenge. Believe it or not, an
elephant's enormous ears (weighing up to 110
pounds each), while exceptionally good at picking
up sound, are also used as an air conditioner of
sorts. When the temperature rises, elephants flap
their ears. This cools blood flowing through
vessels in the ears, which then flows back to the
body, cooling it in turn.

8Giraffe
- Giraffes have many obvious physical adaptations
to help them survive in the African savannas.
9Giraffe
- Camouflaged coat - Patches of different sizes and
colors help hide the giraffe in the African
savanna. - Fringed tail - A fringe at the end of the tail
keeps flies and other pests away.
10Giraffe
- Long neck - It is used to reach leaves in tall
acacia trees. - Long front legs - Unlike many animals, the
giraffe's front legs are longer than the hind
legs. These long front legs make it easier to
reach tall leaves.

12Echidna
- An Echidna is a mammal and is also known as the
Spiny Anteater. An Echidna's body is covered with
long sharp spines set in short fur. These spines
are the Echidnas defense mechanism. When
attacked, it rolls itself in a tight ball and
burrows out of reach.
13Echidna
- Echidnas have no teeth, but uses a long sticky
tongue to penetrate ant and termite nests, which
they have gauged open with their strong ripping
claws.
14Echidna
- Shelter is where ever the echidna finds it and
this could be in logs, under bushes or in caves.
They are 35 - 45 cms long and can weigh 2-7 kg.
The Echidna has a spur on its ankle but it is not
poisonous.

16Gecko
- At 28 cm long, The Round Island Day Gecko is the
largest of 27 species of day geckos. The smallest
day gecko is only about 8 cm long. Most day
geckos are bright green in color. The Round
Island Day Gecko is probably the dullest looking
one of all. It lives on palm trees and is
perfectly camouflaged against the brown bark of
the main stem of the tree.
17Gecko
- Geckos have special feet to help them climb up
smooth surfaces. The flattened toes have
elongated scales. A microscopic view would show
thousands of tiny, hooked bristles that can hold
on to any surface. This means they can easily
climb up palm trees, as well as hide on the
underside of leaves.
18Gecko
- They also have sharp teeth to penetrate the
exo-skeleton of an insect. If attacked, Round
Island Day Geckos have a unique way of defending
themselves.
19Gecko
- The tail just drops off and lies moving around on
the ground. Hopefully the enemy will pay
attention to the tail while the gecko escapes.
The stump quickly heals, and they will eventually
grow a new tail.

21Kangaroo
- These animals are mostly found in the dry inland
Australia, including desert, grassland, mallee,
and mulga country. It is able to go with out
drinking as long as green grass is available and
it adapts well to drought.
22Kangaroo
- Despite its name, the Red Kangaroo is sometimes a
blue-grey color, particularly the female. Even
though these animals look cuddly, they are to be
approached with caution. They have evolved with
a large claw attached to its hind leg.
23Kangaroo
- Red Kangaroos can hop as fast as 40 mph (64 km).
They use this as their first line of defense.
Kangaroos have a tendon in the leg which acts
like a rubber band, conserving energy as the
animal moves lands. Red Kangaroos actually
expand less energy in locomotion as they move
faster, up to very fast speeds.

25Shark
- A shark is a fish. It breathes through its gills,
has a backbone and lives in water. However,
unlike all other fish, its skeleton is made from
cartilage, not bone and they do not have scales
but denticles. Also, they have five to seven gill
slits rather than one each side as in bony fish.
26Shark
- Sharks can detect one part of blood per ten
billion parts of water that means they could
detect one drop of blood in an area the size of
an Olympic swimming pool! The nose of a shark is
only used for smell, unlike in humans where we
also use our noses for breathing.

28African Wild Dog
- Location South Africa and east of Sahara
29African Wild Dog
- Wild dogs have a canine body shape like a wolf's,
but they have larger, bat like ears and white
tipped tails. They have splotches of black,
yellow, white, and dark brown, with no two dogs
marked exactly the same.
30African Wild Dog
- Wild dogs have a highly developed social
structure. They live in packs that vary from 10
to 15 animals, including males, females, and
young. Their packs are nomadic, and they roam
across a range of 1 to 30 miles a day. Members
of the pack cooperate when hunting and raising
their young.
31African Wild Dog
- Wild dogs have developed incredible speed and
endurance for attacking prey. They have been
clocked at running 37 miles per hour for
distances over 3 miles. They also have
specialized, large, bat like ears that allow for
excellent auditory ability used for hunting and
ritual ceremonies

33Lion
- A lion's roar can be heard up to 5 miles away.
Roaring is believed to have a territorial
function and to help animals locate each other.
34Lion
- Territories are scented marked with urine, feces,
and head rubbing. Lions mark with their claws on
trees and other signposts. The mane of the male
provides protection from the claws and teeth of
other males.
35Lion
- They eat anything they can catch and kill, and
groups have even been observed killing
rhinoceros. A lion can eat up to 35 grams of meat
at a sitting. They drink freely when water is
available, but they can survive only on the water
they get from their prey for long periods of
time.
36Lion
- Lions can run at speeds over 30 mph, but only
over short distances. This speed is insufficient
for catching a large antelope, so group stalking
is an important hunting strategy. Lions appear to
assess how much effort will be required for
taking down a particular target, and if the prey
is small enough to be taken by a single female,
the other members of the hunting group will let
her catch it alone.

38Polar Bear
- Polar bears have thick white fur. Their fur and
layers of fat beneath their skin protect them
from the Arctic cold. Their fur also provides
camouflage when they are hunting. Polar bears
have a keen sense of smell. They can smell food
as much as 10 miles away. On land polar bears can
run for short bursts at speeds of up to 35 miles
per hour.
39Polar Bear
- They hunt seals such as the ringed seal and other
animals for food.

41Skunk
- Sometimes the skunk will dig its own den, but it
may also move into another mammals den. Skunks
also live under old buildings. The skunk drags
dried leaves and grass into its burrow to make a
mat. In the winter, it might form a ball of grass
and push this into the door of the den to keep
out the cold wind.
42Skunk
- The skunk is the size of a house cat. Its eyes
ane ears are small. It can not see too well, but
its sense of hearing is good. During the day, a
skunk sleeps. It hunts at night, walking slowly
along, catching insects and looking for small
fruit. It also eats meadow mice, gophers, moles,
and chipmunks.
43Skunk
- The skunk has musk glands and can shoot a liquid
that has a terrible odor.First, it gives a
warning when something approaches it. With its
legs stiff, the skunk stamps the ground with its
feet, snaps its teeth, and its hairs stand
up.Then,if necessary, the skunk swings its rear
end round , lifts its tail up out of the way and
shoots its musk. The liquid can shoot out as far
as four meters. If it hits the enemy in the eyes,
the enemy cannot see for a few moments.

45Zebra
- Each zebra has its own stripe pattern. The zebras
recognize each other by their stripe pattern and
by their smell. Some species have narrow close
set stripes, while others have broader stripes. - Zebras like to help groom each other.
46(No Transcript)
47Zebra
- Zebras are black with white stripes. If you
shaved a zebra, you would see that its skin is
black
