The Danger Below! series is not for the faint of heart. Each of these high-interest volumes introduces basic facts by way of an intense fiction comic, divided into three brief chapters, about people being “attacked” by specific deep-sea creatures (it’s made clear that the animals aren’t intentionally hurting humans). Dangerous Teeth! involves a scuba diver losing his thumb while trying to feed a moray eel. Floating Misery! sees a lifeguard getting entangled in the long, stinging tentacles of a Portuguese-man o’ war. Killer Tentacles! features beach-going children encountering box jellyfish. In Needles of Pain!, a surfer steps on a stonefish camouflaged as coral. Each comic intersperses facts naturally enough into dialogue and captions, as well as in a back-matter spread that pairs more information about the subject with full-color photography. Anderson’s illustrations are made accessible for early-level readers thanks to simple paneling, clear visual cues, and limited detail. Despite blood spurts, scarring, and other very real consequences to the underwater attacks, all the victims here pull through, and Buckley includes some information on surviving, namely applying vinegar to stingers and getting to a hospital. Back matter rounds things out with a glossary, index, further reading, and examples of similarly dangerous fish. Brisk, visual storytelling makes these dramatic shorts suitable to a certain kind of high/low reader interested in specific marine life.
