Animal Adaptations
Week 6 Seminar – SC300 Instructor: Rochelle Troyano

2. REPRODUCING is the important part!
What is an adaptation?
Anything that helps an organism to survive and successfully reproduce in its environment.
REPRODUCING is the important part!

3. The Types of Animal Adaptations are:
Structural Adaptations
Protective Coloration or Camouflage
Mimicry
Behavioral Adaptations
Migration
Hibernation

4. Structural Adaptations
This involves a part of the animal’s body, such as size or shape of the teeth, it’s body covering, or the way it moves

5. Structural Adaptations
The African Lion – (Panthera leo)
Thick mane
coat color
Eyes in front
Heavily muscled forelimbs and shoulders
long, retractile claws
Rough tongue
Resonating roar
Loose belly skin

6. Structural Adaptations
Beaver
(Castor canadensis)
Their noses and ears have valves that close when beavers submerge.
The beaver's incisors protrude in front of their lips, enabling them to cut and chew submerged wood without getting water in their mouths.
Their broad tails function as rudders, helping beavers to maneuver large logs to their lodges and dams.

7. Structural Adaptations
Giraffe
(Camelopardalis reticulata)
Their very long necks are an adaptation to feeding at high levels in the treetops.
The neck veins contain valves and a network of tiny veins to prevent blackouts when the animal lowers its head to drink.
In addition to keeping track of predators, their extreme long-range visual acuity enables visual communication with other giraffe over several miles.
Giraffes can run at speeds up to 35 mph.

8. Structural Adaptations
Polar Bears
(Ursus Maritimus )
Huge size (weigh as much as small automobile (1000 pounds) fierce predators.
large furry feet.
Strong swimmers and can stay submerged for two minutes at a time.
Their fur is made of hollow hairs which trap air and help to insulate them in the frigid waters. 
Their white coats are made up of water repellent guard hairs combined with a dense underfur that covers to the bottom of their feet

9. Structural Adaptations
Caribou
(Rangifer tarandus )
Caribou have developed large, concave hoofs that spread widely to support the animals in deep snow and soft tundra and function well as paddles when they swim.
Short tails
Small ears
Compact bodies
Two layers of fur

10. Structural Adaptations
Moose
(Alces alces)
Long legs
Thick body
Antlers that scoop up water plants – as an attractant to mates
Two layers of fur
Hollow hairs
Paddle like hooves

11. Protective Coloration (Camouflage)
Camouflage helps an organism blend in with its surroundings. Camouflage can be colors or patterns or both. When organisms are camouflaged, they are harder to find. 

12. Protective Coloration (Camouflage)
Blending into areas with light and shadow or with background

13. Protective Coloration (Camouflage)
Blending into the Background
Snow-shoe Hare (Lepus americanus)

14. Protective Coloration (Camouflage)
Blending into the Background
Arctic Fox (Alopex lagopus )

15. Protective Coloration (Camouflage)
Blending into the Background
Willow Ptarmigan (Lagopus lagopus )

16. Protective Coloration (Camouflage)
Blending into the Background
A canyon tree frog on a canyon wall (left) and a desert horned lizard on a sandy riverbed.

17. Protective Coloration (Counter Shading)
Different colors on their backs and stomachs. 

18. Mimicry
Some animals and plants look like other things -- they mimic them.  It can protect the mimic from predators or hide the mimic from prey. 

19. Mimicry The viceroy butterfly mimics the monarch butterfly.
The monarch butterfly doesn't taste very good and most predators will avoid it.  They also avoid the viceroy because it looks like the monarch.
Could You Tell the Difference?

20. Mimicry
The Moth Caterpillar looks like a snake

21. Mimicry This katydid, like a leaf This lizard looks like a tree trunk
This Polyphemus moth looks like it has fierce eyes!

22. Behavioral Adaptations
Social Behavior - Some animals live by themselves, while other live in groups. 

23. Behavioral Adaptations
Living in Groups

24. Behavioral Adaptations
opossum plays dead. 
A rabbit freezes when it thinks it has been seen. 

25. Migration
Migration-is a behavioral adaptation that involves an animal or group of animals moving from one region to another and then back again. 
Animals migrate for different reasons.  The reasons are as follows:
better climate
better food
safe place to live
safe place to raise young
go back to the place they were born.

26. Migration
Canada Geese

27. Migration Arctic terns can migrate as far as 20,000 miles per year.
The sandhill and whooping cranes are both capable of migrating as far as 2,500 miles per year, and the barn swallow more than 6,000 miles.

28. Hibernation
Deep sleep in which an animal's body temperature drops to about the temperature of the environment.  Body activities, such as heartbeat and breathing are slowed causing the animal to need very little food. 
Animals that hibernate are:
bats 
woodchucks
snakes 
bears.
During the hibernation the animals live off of the fat that is stored in their body. 

29. Hibernation

30. Let’s Try to Adapt! When I say go…….
Talk about the weather with your classmates for 5 minutes.
Don’t use any words with the letter “e”

31. How Hard Was It? Compare with a changing environment
Is our environment changing now?
What species will stay around and which will not?

32. Questions?
