Do you know that water covers nearly 70 percent of the earth and that nearly 70 percent of the human body is made up of H2O? That more than half of the earth's species live in water? Or that the sea reflects the sky, so is most often blue, but can also appear green, gray, turquoise, or brown, depending on light, algae, or plant life? With its witty pen and ink illustrations, each page of this activity book engages readers of all ages with fun facts about the intricate world of the sea.Readers learn how to fold an origami boat, sketch fantastical fish and draw daring tattoos on a sailor's arm, while discovering more about the substance that is so essential to our lives that it's sometimes called “Adam's ale”.

How would you color in a drawing of the sea? Well, it depends on whether it is at night or at sunrise. Ostensibly an activity book, this volume is full of subtle marine-themed lessons about physics, geography, biology, and, of course, color theory. -Metropolis
