Have you ever wondered how animals are able to survive in the
wild?
Animals have certain adaptations that help
them to survive.

Think about the way you dress in the winter.
You don’t wear your shorts and bathing suit when it’s snowing outside!
You wear warm clothes, and maybe even a hat and mittens to protect
yourself from the weather.

And what if you are having a snowball fight?
You probably run away from the person throwing at you,
and maybe even try to sneak up on that person and
throw some snowballs!

The way you dress in the winter, as well as the way that you run and hide from
someone throwing snow at you are kinds of …
Adaptations.

ADAPTATIONS
Anything that helps an organism survive in its environment is an adaptation.
![Page 7: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/7.jpg)
We can separate adaptations into two categories:

Structural adaptations
are body feature that allow an animal to find and consume food, defend itself,
and to reproduce its species.
Structural adaptations help an animal survive in its environment.

stick. I look just like a
stick you’d find on the
ground.

Structural Adaptation: Protective Coloration / Camouflage
• Coloration and Protective Resemblance allow an animal to blend into its environment.
• Another word for this is
camouflage. An organisms camouflage makes it hard for enemies to single out individuals.

Structural Adaptation
Camouflage (use of color in a surrounding)
The chameleon can change its color to match its surroundings.

Structural Adaptations: Mimicry
MimicryMimicry allows allows one animal to one animal to look, sound, or look, sound, or act like another act like another animal to fool animal to fool predators into predators into thinking it is thinking it is poisonous or poisonous or dangerous.dangerous.

Mimicry (looking or sounding like another living
organism)
The Viceroy butterfly uses mimicry to look like the Monarch butterfly. Can you tell them apart?
Poisonous
Not poisonous
Structural Adaptation
I’m the Monarch!
I’m the Viceroy!

Chemical defenses (like venom, ink, sprays)
Structural Adaptation

Body coverings & parts (claws, beaks, feet, armor plates, skulls, teeth)
Structural Adaptations
The elephant’s trunk is a structural adaptation that helps it to clean itself, eat, drink, and to pick
things up.

Now let’s learn about
Behavioral Adaptations…
Behavioral Adaptations allow animals to respond to
life needs.
![Page 16: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/16.jpg)
Behavioral Adaptations
• Behavior Adaptations include activities or actions that help an animal survive.
EX:Behavior for protection
• Opossum plays dead
• Rabbit freezes when it is seen
![Page 17: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/17.jpg)
Each organism has unique methods of adapting to its environment by means of
different actions.
Behavioral Adaptations are animals’ actions.
Remember that Structural Adaptations are body features.
![Page 18: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/18.jpg)
We can divide Behavioral Adaptations into two groups:
Instinctive Learned
These behaviors happen naturally & don’t have to
be learned.
These behaviors must be taught.
![Page 19: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/19.jpg)
Instinctive behaviors
happen naturally &
don’t need to be learned
=
Finding shelter
Methods of gathering & storing food
Defending oneself
Raising young
Hibernating
Migrating
![Page 20: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/20.jpg)
Hibernation• This is deep sleep in which animal’s body temp drops
and body activities are slowed to conserve energy.
• EX. Bats, woodchucks, & bears.
![Page 21: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/21.jpg)
Migration• Animals migrate for different
reasons.
– better climate
– better food
– safe place to live
– safe place to raise young
– go back to the place they were born.
• This is a behavioral adaptation that involves an animal or group of animals moving from one region to another and then back again.

Learned behaviors
Obtained by interacting with the environment and cannot be
passed on to the next generation
except by teaching.

Learned Behavior
• Capuchin monkeys always finds the heaviest rock to break the nuts they eat.
• This skill is taught to younger generations…LEARNED BEHAVIOR
![Page 24: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/24.jpg)
In this lesson, we have learned about animal adaptations.
There are 2 ways to describe adaptations:
Structural and Behavioral
![Page 25: Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive](https://reader036.vdocuments.net/reader036/viewer/2022062407/56649d975503460f94a8087f/html5/thumbnails/25.jpg)
Structural adaptations are body features.
Some examples of structural adaptations are:
Camouflage
Mimicry
Body coverings & parts
Chemical defenses

Behavioral Adaptations are animals’ actions.
Behavioral Adaptations can beInstinctive or Learned.

The next time you read about an
animal in the wild, or when you see one on television, think about its adaptations….
