Animal Adaptations Provided by: City of Corpus Christi Museum of Science and History

2 What is an adaptation? An adaptation is a change in an animal’s physical structure or behavior that helps an animal to survive in their habitat. Examples: The shape of a bird’s beak, number of fingers and toes, or the color of an animal’s fur. Physical adaptations do not develop during one lifetime, but over many generations.

3 Example of Adaptation The shape of an animal’s teeth is related to its diet. Herbivores, such as deer, have many molars for chewing tough grass and plants. Carnivores, such as lions, have sharp canines to kill and tear meat.

4 Who experiences adaptations?
All species have experienced adaptation and will continue to slowly adapt as the next generations are born. We will identify certain species from each of these groups and the reasons for their success because of adaptations: Mammals Birds Reptiles Amphibians

5 Mammals Endothermic or warm-blooded All have some type of “hair”
Some are very specialized, such as white polar bear fur Method of locomotion Care for young

6 Birds Leg Length Foot Webbing Beak Shape Roseate Spoonbill (top right)
Laughing Gull (top left) Beak Shape Long Billed Curlew (bottom)

7 Reptiles Ectothermic or cold- blooded Scales
Some undergo hibernation and aestivation Lay eggs on land Leg structure and position

8 Amphibians Ectothermic Lay eggs in water
Partially of fully webbed feet Have lungs or can absorb oxygen through their skin

9 Animal Defense Some animals use these methods of defense to protect themselves: Camouflage Snake Mimicry Mexican Milk Snake Bright colors Skunk and Poison Arrow Frog “Hair” projections Hedgehog quills Deer Antlers

10 Adaptation Applications: Lions
Why are the eyes of a lion set in front of the head rather than on the sides? Answer: Eyes in front of the head allow for depth perception and ability to judge distances when hunting.

11 Adaptation Applications: Lions
What is the purpose of the mane on a male lion? What is the reason for the lion’s color? A thick mane helps the male to appear larger and serves as protection for the throat. The tawny brown coat color camouflages the animal and young among vegetation.

12 Adaptation Applications: Giraffe
Why are giraffes able to go for long periods of time without water? Answer: Giraffes drink water when available, but can go weeks without it. They rely on morning dew and the water content of their food.

13 Adaptation Applications: Giraffe
How are their long necks adapted to their lifestyle? Answer: This extra length is thought to have evolved to help the giraffe spot other giraffe and predators in the distance. It also help with consumption of vegetation that is higher in elevation. Interestingly, giraffes and humans have the same number of vertebrate in their necks.

14 Adaptation Applications: Zebras
How do zebras defend themselves? Capable of running up to 40 mph. Zebras defend themselves by kicking and biting. Coloration also plays a role in evading predators, although theories have not reached an agreement.
