2.  Type of Adaptation
Structural – relating to an organism’s shape, size or structure
 What are the Adaptation
3cm thick layer of fat. Waterproof feathers. Shape of body. Shape of wings. Webbed
feet.
 How does the Adaptation help it to
survive
- The 3cm thick layer of blubber (fat)
- Waterproof feathers keep them warm in winter.
- Webbed feet for powerful swimming.
- Their bodies are streamlined to reduce drag in water.
- Their wings are shaped like flippers so let them swim at speed of 15 mph.
- Keep high body temperature to stay active.
- Dark coloured feathers absorb heat from the sun, which helps to keep them warm.

3.  Type of Adaptation
Behavioural – relating to how an organism acts
 What are the Adaptation
River Red Gum tree’s are able to survive in very tough environments. They are one of
the only tree’s that can survive in floods for a long time.
 How does the Adaptation help it to
survive
- The River Red Gum Tree is an opportunistic water user, and transpires water
whenever it is available.
- Internal oxygen transport and the ability to take oxygen in through the trunk. Very
handy when the roots are flooded and still need oxygen to respire.
- Development of floating root masses to extract oxygen from the air during floods.
- Specialised root tissue to extract water from sandy lenses in the (clay) soil during dry
times
