In a mix of fanciful cartoon panels and narrative snippets, Kaner and Nicholls sound the alarm about 10 invasive species. As creatures from nutrias and cane toads to tawny crazy ants and killer shrimp mug ferociously in the art, Kaner explains with much hand-wringing how each was introduced to a new locale by either hitchhiking in or being released by a well-meaning importer, to the detriment of native species and ecosystems. The concern is certainly justified (even if humans, the most destructive ones of all, didn't make the cut), but not only are the entries subject to occasional carelessness with facts--no, feral cats are not native to Europe--but remediation strategies are often facile, with suggestions like having farmers control ants by getting rid of aphids and holding a contest to design a ship that would somehow prevent potential pests from hitching a ride. Still, the message that it's a bad idea to release imported pets certainly gets its proof here (see: starlings, northern snakehead fish, and the titular pythons), and the author's "If you were a scientist or conservation officer, WHAT WOULD YOU DO?" challenge at the end of each profile may well motivate constructive thinking. Nicholls adds human figures with a range of skin tones to the panels and larger scenes of animal invaders and victims. A lightweight introduction to an increasingly serious issue.

Invasive species are a relatively common topic in nonfiction books for kids, but this volume presents the information in an inviting comics format. Two house pets, a dog and a guinea pig, frame the discussion, presenting an array of animals from the familiar (Burmese python, starlings) to the unfamiliar (cactus moth, killer shrimp) to the thought-provoking (feral cats). Each chapter opens with a brief explanation of the animal's destructive behaviors, as well as maps, diagrams, and a recurring reminder to contact local fish and wildlife departments if the animals are spotted in North America. Playful comics panels (testimonials from affected native species; a courtroom scene where killer shrimp attempt to defend themselves) keep the tone light but emphasize the real damage these animals can do in their non-native habitats. Tips for preventing the introduction of invasive species as well as robust back matter, including a glossary and further reading list, close out this informative volume. A strong pick for fans of the popular Science Comics series.
