How are penguins eyes?
Penguins have a flattened cornea that refracts light less strongly than human or fish corneas. Their strong eye muscles change the shape of their eye lens to create a sharp, clear image both on land and in water. In addition to this, penguins have a nictitating membrane, also referred to as a third eyelid.
What do penguins see underwater?
Penguins need to be able to see clearly on both land and underwater, so neither cornea shape will do. Instead they actually have corneas that are much flatter, even than ours. This takes almost all the focussing power away from the cornea and nearly all the work is done by the lens.
How do penguins see underwater for kids?

Hearing. As in most birds, penguin hearing is probably good, but not as acute as that of marine mammals. One study on African penguins found a hearing range of 100 to 15,000 Hz with a peak sensitivity between 600 to 4,000 Hz.

How are the legs and feet of a penguin important?
Their legs and feet, located far back on the body, contribute to the waddle on land, but underwater they act as streamlined rudders that minimize drag. At the water’s surface a penguin can at best paddle like a duck, but below the waves penguins cruise at speeds faster than Olympic swimmers.
