Question

Presences of spindle shaped body with pneumatic bones is

• A. Fossorial adaptation
• B. Cursorial adaptation
• C. Dessert adaptation
• D. Volant adaptation

Answer 1

The correct option is D Volant adaptation

• Fossorial adaptation is seen in animals that live mostly underground.
• Cursorial adaptation is seen mostly in animals that are adapted to run.
• Desert adaptation is seen in animals that have adapted to the hot and dry environment such as camel.
• Volant adaptation is seen in animals that have adapted to a flying mode of life such as birds. Pneumatic bones are bones that are hollow or contain many air cells. Birds have pneumatic bones that help reduce the skeletal weight in birds. This together with a spindle-shaped body helps the birds in flight. Spindle-shaped bodies with pneumatic bones are therefore characteristics of animals that are adapted to flight.

Thus, the correct answer is 'Volant adaptation.'
