Penguin:

A Penguin is a bird that has wings but can’t fly, however it uses its wings to swim underwater. They are kind of birds that do not fight and spend nearly whole of their lives in the Sea. Countless penguins survive in the freezing water in Antarctica.
They rarely stay on the land except to raise their little ones. Penguins stand straight on their two feet and seem uncomfortable while walking, however they actually walk as fast as humans. Penguins can swim through the oceans, can climb icy mountains by hoping and can travel over slippery ice by sliding on their tummies. Also They eat a range of Deep Sea Fish, squid and krill.
