1. BIRDS PENGUINS

2. Little Man in a Tuxedo
Their hesitant waddle on land, however, belies a penguin's ability in the water.
With streamlined bodies, a thick coat that keeps out the cold and repels water, and flipperlike wings, naturally penguins spend most of their lives in the water.

4. Penguin Parenthood
Penguins breed in colonies, and males and females take turns tending to the one or two eggs that are laid per season.
While the off-duty parent goes in search of food, the guardian parent supports the egg between the top of its feet and a thick fold of skin that hangs from its belly to keep the incubating egg warm.

6. Built-In Waterproofing
Penguins preen their feathers meticulously to maintain insulation and waterproofing.
A gland near the penguin's tail secretes oil into its feathers, which the bird will spread thoroughly while preening.
