Where can you find a world of scaly terrorists, tricksters, brilliant disguises, and built-in fishing lures? Rivers and oceans contain inhabitants that are experts at camouflage, living in severe conditions, or enlisting extreme trickery to hunt for food or avoid predators. This book, part of QEB Publishing's "Awesome Animals" series, uses colorful close-up photography to feature amazing fish. Some of these include the Blackfin icefish that survives living in sub-zero temperatures because it contains a sort of antifreeze in its blood to prevent ice crystals from forming. Tripod fish, dwelling at the bottom of equatorial waters, balance on three long fins and wait for crustaceans—prey—to bump into its fins. The Umbrellamouth gulper eel has a mouth so big, it can swallow prey that are bigger than the eel itself. A Hagfish can make itself a thick, slimy coating to discourage predators. And so on. Each page has a sidebar—"foul facts"—that offer additional information. The book includes an index and a glossary, plus an art project, While the use of alliteration—"funky fishing," "peculiar predators," "vicious vampires," "tricky travelers," and so on—may attract young readers' attention, do we really want children to think of aquatic creatures as freaky, foul peculiar, weird, etc.? Why use negative terms to describe some of the best-adapted, remarkably evolved animals on the planet? Adding the "ugh!" factor to non-warm-and-fuzzy animals hardly ensures their futures.
