Feathers and Locomotion Flashcards
page 63-64
What are the six types of feathers, and their functions?
Contour (shape/insulation), down (insulation), semiplume (beneath contour, insulation), flight (aiding flight), bristle (protection/feeding), filoplume (monitoring feather alignment).
What are the primary functions of flight feathers?
To provide lift and strength for flight.
How do contour feathers benefit a bird?
They streamline the body, aiding in flight and insulation.
Name two adaptations that allow cheetahs to run quickly.
Long limbs and a flexible spine.
What adaptation allows birds to fly?
Hollow bones with a honeycomb structure reduce weight.
How are the limbs of climbers, like monkeys, adapted?
Long limbs, opposable thumbs, and prehensile tails improve grip and mobility.
What is the role of a dolphin’s tail in locomotion?
It provides propulsion for swimming.
How do gliding animals like flying squirrels move through the air?
They use a patagium (fold of skin) to glide between trees.
