Structural Adaptations are physical features of an animal's body that help it survive in its environment. These adaptations can involve:
* Body shape: This can affect how an animal moves, interacts with its surroundings, and even its temperature regulation. For example, a fish's streamlined body helps it swim efficiently, while a polar bear's thick layer of blubber keeps it warm in freezing Arctic waters.
* Body coverings: Fur, scales, feathers, or shells can provide insulation, protection from predators, or camouflage. A cheetah's spots help it blend into the grasslands, while a porcupine's quills provide defense.
* Internal organs: The size and structure of internal organs can also be adaptations. For instance, a camel's ability to store water in its hump helps it survive in desert environments.
* Appendages: Special limbs or body parts, like a bird's wings, a snake's forked tongue, or a monkey's prehensile tail, can help an animal obtain food, navigate its environment, or defend itself.
Examples of Structural Adaptations:
* The long neck of a giraffe: Allows it to reach leaves high in trees that other animals can't access.
* The sharp claws of a lion: Help it to hunt and capture prey.
* The webbed feet of a duck: Enable it to swim efficiently in water.
* The camouflage of a chameleon: Allows it to blend into its surroundings to ambush prey or hide from predators.
Key Takeaways:
* Structural adaptations are physical features that help animals survive.
* These adaptations are often directly linked to an animal's environment and lifestyle.
* They are the result of evolution and natural selection.
