The life of penguins. Penguins stand upright on land and walk with a waddle because they have short legs and tall, torpedo-shaped bodies.
Penguins appear awkward out of the water, but they can walk about as fast as a human being.
They also climb rocky slopes easily, sometimes hopping from rock to rock. Penguins lost the ability to fly millions of years ago. As they began to spend most of their time in the water, their wings started to look more like flippers. This major change helped make penguins excellent swimmers. The body of a penguin is specially suited to living in the sea.
