Reese (entomology, Virginia Tech-Blacksburg) provides information about creatures that are commonly encountered in the shallows of freshwater environments and are large enough to be seen with the naked eye. One section focuses on identification and the other on additional information about the creatures. Although much is accessible to school-age students, the book has enough depth and breadth to appeal also to an adult audience, including environmental educators, anglers, and natural history aficionados.
