Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive. © A. Weinberg
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. © A. Weinberg
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! © A. Weinberg
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: are changes animals go through so they can survive © A. Weinberg
We can separate adaptations into two categories: A D Physical A P T A AND T I O N © A. Weinberg S Behavioral
Physical adaptations are body structures that help them survive Hey! I’m a walking stick. I look just like a stick you’d find on the ground. Physical adaptations help an animal survive in its environment. © A. Weinberg
Physical adaptation Camouflage : hides by blending in with its surroundings (use of color in a surrounding) The chameleon can change its color to match its surroundings. Can you do that? © A. Weinberg
Physical adaptation Mimicry: copy other animals. (looks or sounds like) Some moths have spots that look like eyes to scare away predators. 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! © A. Weinberg A mockingbird mimics the songs of other birds.
Physical adaptation Unique Defenses: special ways animals fight other animals, or how it avoids a confrontation Opossum plays dead. A puffer fish puffs up its stomach with air. Skunks spray a terrible odor. Octopuses spray a dye that is poisonous. © A. Weinberg
Physical adaptations Special Adaptations: features that help an animal survive Ex: Body coverings, shape, size, & parts (claws, beaks, feet, armor plates, skulls, teeth, fat, fur, wide flat feet, large ears…) © A. Weinberg The elephant’s trunk is a physical adaptation that helps it to clean itself, eat, drink, and to pick things up.
Metamorphosis Changes organisms go through from birth to death. (Complete & Incomplete) Ex. Butterfly, Frog, Plant, Beetle, Humans © A. Weinberg
Now let’s learn about Behavioral Adaptations… Behavioral Adaptations allow animals to respond to life needs. © A. Weinberg
Behavioral Adaptations are animals’ actions. Remember that Physical Adaptations are body structures. Each organism has unique methods of adapting to its environment by means of different actions. © A. Weinberg
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. © A. Weinberg
Instinctive behaviors Methods of gathering & storing food Finding shelter © A. Weinberg = happen naturally & don’t need to be learned Defending oneself Raising young Hibernating Migrating
Migration: to move from one location to another when the seasons change. Hibernation: inactivity (sleeplike state) during winter. During hibernation, the animal’s temperature decreases, and its breathing & heart rate becomes very slow. © A. Weinberg
Learned behaviors = Obtained by interacting with the environment and cannot be passed on to the next generation except by teaching. Example: Baby ducks watch their mom to learn where to swim and what is safe to eat. Prairie dogs learn warning signals from parents. Dogs can be trained to do tricks. © A. Weinberg
In this lesson, we have learned about animal adaptations. There are 2 ways to describe adaptations: Physical © A. Weinberg and Behavioral
Physical adaptations are body structures. Some examples of physical adaptations are: Camouflage Mimicry Unique defenses Special Adaptations © A. Weinberg
Behavioral Adaptations are animals’ actions. Behavioral Adaptations can be Instinctive or Learned. © A. Weinberg
The next time you read about an animal in the wild, or when you see on television, think about its adaptations…. © A. Weinberg
