BUBBLE HOMES AND FISH FARTS

Bayrock’s love of “way cool science” bubbles over in this surprisingly substantial book. How do animals use bubbles? For sailing, running, breathing, nesting—even playing (dolphins seem to blow bubbles just for fun). Sixteen double-page spreads cover 16 wholly different ways that fish, insects, amphibians and mammals use bubbles. Did you know that one species of spider creates a bubble home to live in underwater? That the popping bubbles of snapping shrimp can be “so loud it gets in the way of U.S. Navy sonar”? That the water shrew can actually run across the surface of the water courtesy of the bubbles trapped between its hairy toes? Lively expository prose deftly combines straightforward facts (the scientific name of each animal), sound effects (the “fwap-fwap-fwap-fwap” of tree frogs creating foam) and kid-friendly comparisons (the gourami fish spitting eggs into its nest looks like it’s playing basketball). Conahan’s whimsical watercolor illustrations, complete with conversational bubbles, add humor and interest. Three pages of additional facts and a combined glossary/index round out a volume that’s sure to rise to the top. (Informational picture book. 5-10)
