Study Notes
Penguin Physiology
- Penguins are covered in dense feathers, providing waterproofing and insulation.
- A thick layer of fat (blubber) under their skin helps maintain body warmth in icy environments.
Penguin Feet Adaptation
- Penguin feet lack feathers, exposing them directly to cold temperatures.
- Blood vessels are structured to regulate temperature:
- Cold blood is transported up from the feet.
- Warm blood from the body circulates down to the feet.
- These blood vessels intertwine, enabling heat exchange to keep feet warm.
Habitat of Penguins
- Penguins primarily reside in Antarctica, one of the coldest regions on Earth, adapted to extreme conditions.
Polar Bear Characteristics
- Polar bears have thick fur and a layer of fat for warmth, allowing survival in harsh Arctic climates.
- Their thick white fur not only insulates but also camouflages them against the snow, aiding in predation.
Polar Bear Habitat
- Polar bears are found in the Arctic region, where extreme cold and ice conditions prevail.
