Question

what protects penguins wings like other birds​

Answer 1

$\huge\bold\purple{Answer}$

Instead of having wings like other birds, penguins have tapered, flattened flippers for swimming. Penguins propel themselves through the water by flapping their flippers.

Answer 2

Answer:

Penguin's flippers

Wings are modified into paddle-like flippers. The bones are flattened and broadened, with the joint of the elbow and wrist almost fused. This forms a tapered, flat flipper for swimming.

Each flipper is covered with short, scale-like feathers. The long wing feathers typical of most birds would be too flexible for swimming through water.
