3. Adaptations for Movement Animals need to move efficiently in order to hunt for food and escape from danger. We will take a look at how animals adapt to moving in water and in air.

6. Streamlined body shape The bodies of most aquatic animals are streamlined . A streamlined body shape is one that is narrow at both ends, and broad in the middle. This shape enables the animals to swim faster. (E.g. fish, penguin, dolphin) These animals need to swim fast to catch their prey or swim away from predators to avoid being eaten.

16. Flight muscles Birds also have strong flight muscles for flapping their wings.

17. Feathers Birds are the only animals that have feathers . Feathers make light but strong wings, and keep the birds warm. The warmth provided by the feathers ensures that the flight muscles can work properly.

18. Streamlined body shape Just like there is water resistance, there is a force called air resistance that opposes motion in air. When a bird is flying, its streamlined body shape helps to reduce air resistance.

19. Hollow bones Most importantly, birds have bones that are hollow yet strong. This reduces the bird’s body weight and makes flight easier.
