Transcript of Think about the way you dress in the winter. You wear warm clothes, and maybe even a hat and mittens...
Think about the way you dress in the winter.
You wear warm clothes, and maybe even a hat and mittens to protect yourself from the weather.
Think about the way you dress when you and your buddies play
paintball.
• Covers head, shoulders, upper arms & torso
• Fits over paint ball mask
• Designed to add natural vegetation
The way you dress in the winter, as well as the way you dress for paintball are both types of …
•Adaptations!
Animal Adaptations
• What is an adaptation?
• An adaptation is something that helps animals survive better.
We can separate adaptationsadaptations into two categories:
AADDAAPPTTAATTIIOONNSS
Physical Physical
And
BehavioralBehavioral
Physical Adaptationsare body structures that allow an animal to find & consume food, defend itself,
and to reproduce its species.
Physical adaptations
help an animal survive in its environment.
Hey! I’m a walking
stick. I look just like a
stick you’d find on the
ground.
Let’s begin w/Physical Adaptations
Some examples are:
• CamouflageCamouflage• MimicryMimicry
• Chemical defensesChemical defenses• Body coverings & partsBody coverings & parts
CamouflageCamouflage
Camouflage (use of color in a surrounding)
Camouflage • Have you ever
wondered why animals have spots, strips, or certain colors?
• Sometimes an animal’s colors can be a difference between life and death.
• Animals use their colors to blend into the environment.
The chameleon can change its ccoolloorr to match its surroundings.
Can YOU do that?
See if you can find the camouflaged animals in these pictures. The animals you are looking for are a deer, frog, and quail.
Find the critters!
Quail
Deer!
Look closely to find this animal!
Can you see the frog?
Mimicry• Animals may also try
to look like another animals.
• For example, non poisonous snakes will rattle their tale and flatten their head to look poisonous to a predator.
• This is called Mimicry, where an animal tries to mimic or copy another.
Which snake is poisonous?
Other forms of mimicry…• The monarch
butterfly is toxic and very nasty to eat.
• Its bright orange coloration is a warning to birds to leave it alone.
• The non-toxic viceroy butterfly has developed colors and wing patterns that are very similar to those of the monarch
• So most birds won’t take a chance by taste-testing it!
Which is the monarch andWhich is the viceroy?
Chemical defenses (like venom, ink, sprays)

Physical adaptationsBody coverings & parts
(claws, beaks, feet, armor plates, skulls, teeth)
The elephant’s trunk is a physical 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.
Behavioral Adaptations are animals’ actions.
Each organism has unique methods of adapting to its environment by
means of different actions.
We can divide Behavioral Adaptations into two groups:
These behaviors happen naturally & don’t have to be learned
•
These behaviors must be taught.
Instinctive Learned
Methods of gathering & storing food

In this lesson, we have learned about animal adaptations.
There are 2 ways to describe adaptations:
