Multiple Choice

How are bat forelimbs different from the forelimbs of other mammals?

Bat forelimbs are similar to those of aquatic mammals, with webbed digits for swimming.

Bat forelimbs are primarily used for grasping and climbing, similar to primates.

Bat forelimbs are adapted for flight with elongated fingers supporting a wing membrane.

Bat forelimbs are shorter and used primarily for digging.

Verified step by step guidance

Begin by understanding the primary function of bat forelimbs, which is flight. This is a unique adaptation among mammals.

Recognize that bat forelimbs have elongated fingers. These fingers are much longer compared to other mammals, which is crucial for supporting the wing membrane.

Consider the structure of the wing membrane. It is a thin layer of skin that stretches between the elongated fingers, allowing bats to glide and maneuver in the air.

Compare bat forelimbs to those of other mammals. Unlike aquatic mammals with webbed digits for swimming or primates with forelimbs for grasping, bats have specialized adaptations for aerial locomotion.

Understand that the adaptation for flight involves not just the forelimbs but also the entire skeletal structure, including lightweight bones and a keeled sternum for muscle attachment, enhancing their ability to fly.
