A children's author "use[s] traits and developmental milestones of 11 species . . . to take full measure of animal lives . . . As intriguing as it is gorgeous" ( Publishers Weekly, starred review).

In one lifetime, a caribou will shed ten sets of antlers, a woodpecker will drill thirty roosting holes, a giraffe will wear 200 spots, a seahorse will birth 1,000 babies.

Count each one and many more while learning about the wondrous things that can happen in just one lifetime. This extraordinary book collects animal information not available anywhere else—and shows all thirty roosting holes, all 200 spots, and, yes, all 1,000 baby seahorses in eye-catching illustrations. A book about picturing numbers and considering the endlessly fascinating lives all around us, Lifetime is sure to delight young nature lovers.
