Texas has about one hundred twenty native species and subspecies of snakes, fifteen of which are venomous. Since 1950, Texans have turned to the Poisonous Snakes of Texas pamphlet series published by the Texas Parks and Wildlife Department for help in identifying these snakes and for expert advice on preventing and treating snakebite. Venomous Snakes of Texas, a thoroughly revised and updated edition of Poisonous Snakes, carries on this tradition as a one-stop, all-you-need-to-know guide to Texas's rattlesnakes, copperheads, cottonmouths, and coral...

For 150 million years, the skies didn't belong to birds--they belonged to the pterosaurs. These flying reptiles, which include the pterodactyls, shared the world with the nonavian dinosaurs until their extinction 65 million years ago. Some pterosaurs, such as the giant azhdarchids, were the largest flying animals of all time, with wingspans exceeding thirty feet and standing heights comparable to modern giraffes. This richly illustrated book takes an unprecedented look at these astonishing creatures, presenting the latest findings on their anatomy, ecology, and extinction.

Despite their abundance in many parts of North America, salamanders have generally been neglected by all but a few specialists. In this book first published in 1943 Sherman C. Bishop discusses in a lively but authoritative manner the 126 species and subspecies of salamanders that are known to exist in the United States, Canada, and Baja California.

Group by group, Bishop describes salamanders in accounts that give the common and technical names, type of locality, range, habitat, size, anatomical characteristics, color, breeding habits, and relationships all in a uniform arrangement...

Frogs are amazingly diverse--ranging from the massive goliath frog, which weighs several pounds, to the recently discovered gold frog, which measures a mere three-eighths of an inch when fully grown--and have inhabited the earth for more than 200 million years. Today, however, these amphibians face more challenges than any other vertebrate group. In this fun and informative book, herpetologists Mike Dorcas and Whit Gibbons answer common and not-so-common questions people may have about these fascinating animals.

Dorcas and Gibbons discuss how frogs evolved, which species currently...

Who was Richard Kemp, after whom the Kemp's ridley sea turtle is named? Is Wake's Gecko named after Berkeley's Marvalee Wake? Or perhaps her husband, David? Why do so many snakes and lizards have Werner in their name? This reference book answers these and thousands of other questions about the origins of the vernacular and scientific names of reptiles across the globe.

From Agkistrodon piscivorus conanti, the Florida cottonmouth subspecies named for Roger Conant, to Xantusia, the night lizard genera namesake of John Xantus, this dictionary covers everyone after whom an...

Remnants of an ancient lineage, tortoises date back to the Eocene. Among the five species remaining in North America, Texas tortoises are the smallest in size and inhabit some of the harshest arid environments known. They are also the most neglected by wildlife personnel. In The Texas Tortoise, biologists Francis L. Rose and Frank W. Judd draw on decades of research to offer the first comprehensive account of this fascinating but threatened species.
The authors begin by explaining the relationship of the Texas tortoise to other species, fossil as well as extant. They delineate...
