Question

Why do penguins has a large head, short body and elongated body

Answer 1

Answer:

The penguin's body is adapted for swimming. Its body is fusiform (tapered at both ends) and streamlined. A penguin has a large head, short neck, and elongated body.

The tail is short, stiff, and wedge-shaped.

The legs and webbed feet are set far back on the body, which gives penguins their upright posture on land.
