Gr 3-8–Each title in this series introduces eight to 10 animals in terms of their potential danger to humans, other animals, and the environment. A few sentences describe the threats each animal poses, with selected statistics. A “danger meter” rates each one from low to high, and the chosen animals represent a wide spectrum. Invasive species like cane toads receive high danger ratings; mosquitoes rank higher due to the human deaths they cause. Great white sharks are ranked medium high because they “only bite five to ten people a year.” Animals that might look scary, such as turkey vultures and bats, receive low ratings, aptly demonstrating that appearances can be misleading. A single photograph fills each spread, effectively depicting the animals’ fearsome appearance. Some images show the dangerous ones interacting with humans or animals. VERDICT An engaging presentation with high appeal.
