This episode concentrates on the color blue in nature. It shows many plants and animals that are blue in color or has blue on them; everything from blue lobsters and crabs, to blue flowers, to blue birds, etc, etc. It demonstrates the uniqueness of these particular living things in the USA.—George D.

From Bluebells to Bluebirds to Blue Whales -- Nature abounds in examples of this primary hue.

Some explanations are simple -- others quite complex. Beautiful and bold, this is a wild "Rhapsody in Blue".—Anonymous
