Title: Adaptations
1Adaptations
2Definition
- Characteristics that give an organism a better
chance of survival. - Special traits that help living organisms survive
in a particular environment.
3Reasons for adaptations
- To suit their habitat
- For protection
- For attack
- For feeding
- For movement
4Types of adaptations
- Structural external characteristics
- size and shape
- Feet, eyes, bills, skin
- Behavioral - differing ways of reacting to the
environment - Nocturnal
- Arboreal
- Burrowing
5Types of adaptations
- Physiological - internal characteristics
- Hibernation
- Rumination
- Endothermic
6Examples
- Sharp teeth and claws for carnivores
- Flat teeth for grinding and chewing
- Moving in large groups is a behavioral
adaptation it helps protect the members of the
group from predators. - The thick fur coat of an arctic fox is a
structural adaptation. It helps protect it
against the cold weather.

10Habitat Dry inland Australia, including deserts
and grasslands Adaptations It is able to go with
out drinking as long as green grass is available
and it adapts well to drought. They 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. The tail
serves as a balance when the animal leaps and as
a prop when it stands.
11Habitat Frigid seas Adaptations Black and
white colors. These colors help camouflage them.
Their blowhole is at the top of their head. This
enables them to come up and breathe more easily.
Blubber keeps them warm in the frigid
seas. Orcas are the fastest mammals in the sea.
They can go up to 34 mph. Their speed helps them
catch their prey.
12Habitat Wet, humid and hot jungles as well as
icy cold forests Adaptations A tiger's
hindlimbs are longer than the forelimbs, an for
jumping. The forelimbs and shoulders are
well-muscled, and the forelegs can twist inward,
enabling the tiger to grab and hold large prey.
The underside of the paws have soft pads which
allow tigers to quietly stalk their prey.
13Habitat Tropical secondary forest Adaptations
Opposable thumb enables manipulation of objects
big toe also opposable for grasping. Large and
powerful arms used to break stalks or uproot
vegetation while foraging. High intelligence
probably an adaptation for finding scarce or
isolated fruit plants in the rain forest.
14Habitat Dry deserts Adaptations The spines
serve a number of purposes in addition to
protection from hungry and thirsty animals. They
provide shade, serve as a windbreak to prevent
dehydration from dry winds, and help trap warm
air close to the plant. The root systems of
cacti are very close to the surface of the soil,
making it possible for them to take advantage of
the slightest rain shower.
15Habitat Underwater Adaptations Little or no
mechanical strengthening tissue in stems. If
these plants are removed from the water, they
hang limply. They are normally supported by water
all around them and so have no need of mechanical
strengthening. Air-filled cavities often extend
throughout the leaves and stems of aquatic
plants, providing an internal atmosphere.
