Not only does Jenkins (Life on Earth, 2002, etc.) again display a genius for creating paper-collage wildlife portraits with astonishingly realistic skin, fur, and feathers, but here on alternate spreads he zooms in for equally lifelike close-ups of ears, eyes, noses, mouths, feet, and tails. Five examples of each organ thrusting in from beyond the pages’ edges for each “What do you do” question precede spreads in which the point of view pulls back to show the whole animal, with a short accompanying caption. Visual surprises abound: a field cricket’s ears are actually on its legs; a horned lizard can (and does, here) squirt blood from its eyes as a defense mechanism; in an ingenious use of page design, a five-lined skink’s breakable tail enters and leaves the center gutter at different points. Capped by a systematic appendix furnishing more, and often arresting, details—“A humpback whale can be 50 feet long and weigh a ton per foot”—this array of wide eyes and open mouths will definitely have viewers responding with wide eyes and open mouths of their own.
