  • Animal Adaptations
  • Introduction Definition Adaptation in different animals Adaptation in Amphibians, Reptiles, Birds and Mammals. Conclusion SYNOPSIS
  • Adaptation: a structure or behavior that helps a living thing live in its surroundings. Adapted: made fit to live under certain conditions. Protective colorations: colors or patterns on an animal that help keep the animal from being seen by predators. Migration: movement from one place to another when the seasons change. Hibernate: to spend the winter in a state in which the body greatly slows down. Nitrogen: a material that plants need to grow. Annual: a plant that lives only one year. Evergreen: a plant that stays green all year, including firs, spruces, and pines. Perennial: a plant that can live two years or more. Vocabulary
  • An adaptation is a change in an animals physical structure or behavior that helps an animal to survive in their habitat. Examples: The shape of a birds beak, number of fingers and toes, or the color of an animals fur. Physical adaptations do not develop during one lifetime, but over many generations. What is an adaptation?
  • Example of Adaptation The shape of an animals 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.
  • 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: Amphibians Reptiles Birds Mammals Who experiences adaptations?
  • Amphibians Ectothermic Lay eggs in water Partially of fully webbed feet Have lungs or can absorb oxygen through their skin
  • Reptiles Ectothermic or cold- blooded Scales Some undergo hibernation and estivation Lay eggs on land Leg structure and position
  • Birds Leg Length Roseate Spoonbill (top right) Foot Webbing Laughing Gull (top left) Beak Shape Long Billed Curlew (bottom)
  • 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
  • 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
  • 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. Adaptation Applications: Lions
  • What is the purpose of the mane on a male lion? What is the reason for the lions 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. Adaptation Applications: Lions
  • 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. 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 predators and other giraffes in the distance. Interestingly, giraffes and humans have the same number of vertebrae in their necks. Adaptation Applications: Giraffe
  • 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. Adaptation Applications: Zebras
  • This is a very special kind of deep sleep It is brought on by short day lengths, cold temperatures and food shortages It is a survival strategy Dropping into a deep hibernation means animals are using less energy Food is scarce Animals miss the cold seasons What is hibernation? Why do animals hibernate? Email - asifkanth89@gmail.com +919018533143 / +919697167585
  • They try to put on as much fat as possible because they wont be eating much during the winter This is called brown fat, which is found across the back and shoulders, close to an animals organs Brown fat works hard to deliver quick energy to an animal coming out of hibernation How do animals prepare for hibernation?

  • On the whole we can conclude that adaptations are the sum of various physiological or structural modifications that take place in a part or whole body of an organism so that they can accommodate themselves according to their external environment. CONCLUSION
