“Can you tell the difference between a highfin carpsucker and a hornyhead chub? (Hint: they’re both fish.) If not, and if you’d like to be able to, then the expansive Fishes of the Chicago Region is for you. Filled with full-color images of sturgeons, loaches, sticklebacks and smelts, the 500-page tome is a must-have field guide for fans of Second City area fish. . . . Ichthyologists have been studying Illinois fish for more than a century, and there’s a rich history of books about them. But massive ecological changes in the area—redirected waterways, the reversal of the Chicago River in the late nineteenth century—have also caused massive changes in the region’s fish populations. Fishes tells you where these creatures now live and spawn, what they eat, which ones we like to eat and so on. Many of the fish here are lovely, in their way, like the aqua and orange northern sunfish. Others are the stuff of nightmares (sea lampreys, with their circular maws ringed with rows of sharp teeth), while still others, like sturgeons, hail from the age of the dinosaurs, and look it. If many of the common names of the fish sound like hurled insults, the scientific names are even stranger, with Latin elements that roughly translate as ‘forgetting intestine,’ ‘with large buttocks’ and ‘odorous.’”
