Habitat Adaptation Habitat The environment in which a specific species lives in. Example : Canadian beavers live in the wetlands and lakes of North America. Why are habitats important? Needed to meet other animals of the same species in order to reproduce Shelter Food and water To be in a climate to which they are adapted to Adaptation? An adaptation is a way an animals body helps it survive, or live, in its environment Species must be adapted to their habitat Animals depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. These physical features are called physical adaptations. They makes it possible for the animal to live in a particular place and in a particular way. Each adaptation has been produced by evolution. This means that the adaptations have developed over many generations. Examples of the basic adaptations that help creatures survive: shape of a birds beak, the number of fingers, colour of the fur, the thickness or thinness of the fur, the shape of the nose or ears What is a mimicry adaptation? Mimicry is adapting to look like something else. An example would be the hawkmoth as it looks just like a dead leaf, tattered and veined. Example of Adaptations to Climate (p.225) Red fox vs. Arctic fox PENGUINS! Penguins have webbed feet for powerful swimming. Their bodies are streamlined to reduce drag in water. Their wings, shaped like flippers, also help them fly underwater at speeds up to 15 mph. Penguins have to keep high body temperatures to remain active. They have thick skin and lots of fat (blubber) under their skin to keep warm in cold weather. They also huddle together with their friends to keep warm. Emperor penguins have developed a social behaviour that when it gets cold, they huddle together in groups that may comprise several thousand penguins. The dark coloured feathers of a penguins back surface absorb heat from the sun, so helping them to warm up too.
