"Kyphosis and other Variations in Soft-shelled Turtles" by Hobart M. Smith is a scientific publication written in the mid-20th century. As part of the University of Kansas Publications series from the Museum of Natural History, this work explores specific anatomical anomalies observed in soft-shelled turtles, such as kyphosis, a condition that causes a humped appearance in the carapace of these reptiles. The book presents detailed findings from the examination of various soft-shelled turtle species, primarily focusing on three identified American species: "Amyda emoryi", "A. mutica", and "A. spinifera". Smith discusses the characteristics of kyphotic specimens, including their variations in size, shape, and the implications of these anomalies in relation to growth patterns and potential causes. Additionally, it touches on the anatomical distinctions within Soft-shelled Turtles, contributing to the understanding of their classification and taxonomy. The publication is valuable for researchers, herpetologists, and those interested in turtle biology. (This is an automatically generated summary.)
