"Viewfinder: Oceans" reveals the extraordinary world of the deep in amazing detail. Using the removable magnifier included with the book, kids can examine the sharp teeth on a saber fish, the thick spines on a sea urchin, and the stinging tentacles on a jellyfish. When they see the light emitters on a lantern fish, they'll learn how they help it lure prey, and when they see the multicolored bill on the puffin, they'll find out how important it is when digging a nest. More than three-quarters of our planet is covered by water--and with "Viewfinder: Oceans," kids will get to explore it all!
