(3) 4-6 The table of contents gives readers a taste (ew) of what's in store: poop, mucus, spit, gas, and more. Eamer goes beyond the gross hook, however, explaining in an introduction, "Many of these animals actually survive on revolting substances and thrive on gross habits." A lively and accessible page design includes close-up photos, text boxes, and design elements to up the ick-factor. Eamer's detailed text strikes the right balance between intriguingly disgusting facts (hagfish produce slime "by the bucketful in less than a second") and solid information (scientists are looking at using "hagfish slime as a natural replacement for petroleum-based fibers"). "Some gross extras," a glossary, selected sources, and an index conclude this well-organized offering.

Pages also include "Did You Know?" fact sidebars and microbes cracking corny jokes in speech bubbles. Glos., ind.
