Animal Adaptations Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive. I. What is an adaptation? A. 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. B. Physical adaptations do not develop during one lifetime, but over many generations. II. Physical adaptations A. are body structures that allow an animal to find and consume food, defend itself, and survive in its environment. © A. Weinberg Physical adaptation Camouflage (use of color in a surrounding) The chameleon can change its color to match its surroundings. Can you do that? Physical adaptation Mimicry(looking or sounding like another living organism) The Viceroy butterfly uses mimicry to look like the Monarch butterfly. Can you tell them apart? I’m the Viceroy! Not poisonous Poisonous I’m the Monarch! Physical adaptation Chemical defenses (like venom, ink, spines, sprays) Physical adaptations Body 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 are animals’ actions. Behavioral Adaptations allow animals to respond to life needs. 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. Instinctive behaviors = 1. Methods of 2. Defending gathering & storing oneself food 4. Finding shelter happen naturally & don’t need to be learned 3. Hibernating 5.Migrating 1.Migration a. This is when behavioral adaptation that involves an animal or group of animals moving from one region to another and then back again. B. Animals migrate for different reasons. better climate better food safe place to live go back to the place they were born. 2. Hibernation This is deep sleep in which animal’s body temp droops, body activities are slowed to conserve energy. Ex. Bats, woodchucks & bears. Estivation A summer sleep Animals rests in cool or shady areas. Ex – snails, earthworms, bees, snakes Learned behaviors = Obtained by interacting with the environment and cannot be passed on to the next generation except by teaching. B.Mammals 1. Endothermic or warm-blooded A. All have some type of “hair” 1.Some are very specialized, such as white polar bear fur C. Birds 1. Leg Length Roseate Spoonbill (top right) 2. Foot Webbing Laughing Gull (top left) 3. Beak Shape Long Billed Curlew (bottom) D. Reptiles 1. Ectothermic or cold- blooded 2. Scales 3. Some undergo hibernation and estivation 4. Lay eggs on land 5. Leg structure and position E. Amphibians 1. Ectothermic 2. Lay eggs in water 3. Partially of fully webbed feet 4.Have lungs or can absorb oxygen through their skin F. Animal Defense 1. Some animals use these methods of defense to protect themselves: a. Camouflage Snake b. Mimicry Mexican Milk Snake c. Bright colors Skunk and Poison Arrow Frog d. “Hair” projections Hedgehog quills Example of Adaptation The shape of an animal’s teeth is related to its diet. Herbivores, such as deer, have many molars(dull teeth) for chewing tough grass and plants. Carnivores, such as lions, have sharp canines to kill and tear meat.
