| 520 | _a"North American Recent Soft-Shelled Turtles (Family Trionychidae)" by Robert G. Webb is a scientific publication written in the early 1960s. This work provides a comprehensive examination of the genus "Trionyx", which includes various species and subspecies of soft-shelled turtles found in North America. The book delves into their taxonomy, natural history, collecting methods, and evolutionary relationships, aimed at professional biologists and herpetologists. The opening of the text introduces the author’s motivation to study soft-shelled turtles, sparked by his observations while collecting specimens from river systems in the Gulf Coast. Webb raises questions about the geographical distribution and variations among turtle populations, aiming to understand how historical changes in aquatic habitats have influenced the species. He also outlines the methods and materials used in his research, preparing readers for a systematic account of the turtles, their habitats, behaviors, and the significance of their study in the broader context of river ecology and evolution.
