Monitor lizards (genus Varanus) have attracted a great deal of interest--these large and impressive lizards are often the centerpiece of reptile house exhibits. Monitors tend to be fairly wary and difficult to observe--therefore they are not particularly tractable research subjects, but they have nevertheless received an extraordinary amount of attention from devoted students.Varanoid Lizards of the World is a comprehensive account of virtually everything important that is known about monitor lizards, beginning with detailed species accounts and proceeding to various modern comparative analyses. Where possible, people who have had detailed field experience with a particular species have assembled species accounts. In the process of reporting what is known, we also identify what remains to be learned about these lizards. We hope to establish a prototype showing how such a diverse monophyletic group can be exploited both to identify and to understand the actual course of evolution. As such, this effort becomes a protocol for future workers to follow for other groups of closely-related species.

Lizards of the World is ultimate book on these fascinating creatures, featuring the all the different types of lizard worldwide. As survivors from the time of the dinosaurs, lizards are scaly, cold-blooded, living fossils—relics from a prehistoric world that remain alive and well in ours. Lizards exert a morbid fascination, in many mythologies they are dark creatures, symbolizing death and misfortune. From chameleons and skinks to geckos and iguanas, Lizards of the World brings these creatures firmly into the light, to reveal their extraordinary diversity Found in almost every type of terrain globally, there are almost 6,500 species of lizard, including lizards with frills, horns, or wings, those that drop their tails, and others that squirt blood from their eyes. Here, the lizard family and subfamily profiles, organized phylogenetically, are illustrated with stunning photography. Each profile includes a population distribution map, a table of essential information, and a fascinating commentary revealing notable characteristics, fresh scientific understanding, and the diversity of species. Written by world-renowned herpetologist Mark O’Shea, Lizards of the World is a magnificent showcase of the natural history and beauty of these remarkable reptiles.

What caused their extinction remains a mystery, and one that makes an intriguing conclusion to this portrait of a true dragon of the past.

The goanna's ubiquity and sometimes brazen behaviour has made them a familiar favourite with generations of Australian bushwalkers, campers, and picnickers. This updated editon brings together the fascintating natural history of these ancient animals and other members of the family Varanidae, which includes the world's largest lizard, the Komodo dragon.

A lavishly illustrated overview of the world’s lizards Lizards are one of nature’s great success stories: survivors from the time of the dinosaurs, they have taken advantage of almost every habitat on earth, from tropical rainforest to Arctic tundra and even our homes. From chameleons and skinks to geckos and iguanas, there are close to 7,000 species of lizards around the world. This expert guide explores their extraordinary diversity and adaptations. Lizards of the World features an in-depth introduction covering the evolution, anatomy, and lifestyle of lizards, followed by profiles of species from every family, accompanied by stunning color photographs. This invaluable guide highlights the enormous range of habitats, appearance, and activity among lizards. Many thrive in extreme conditions, and have adapted to keep cool, warm, or hydrated. Some can protect themselves by changing color to blend in with their surroundings, while others have fringed toes enabling them to run across sand, or can parachute out of a predator’s reach. Covering diet and reproduction as well as defense strategies and conservation, Lizards of the World showcases the unique natural history and beauty of these remarkable creatures. More than 200 detailed photographic images 80+ lizard families and subfamilies Exploration of lizard biology, behavior, habits, and distribution Broad coverage and in-depth treatment by a world-renowned herpetologist

Originally published in 1992, Giant Lizards is a bestselling reference held in high regard within every level of the herp hobby for its authoritative and thorough coverage of lizard biology. Now in a completely revised and expanded volume, Giant Lizards features all newly written information by an expert on monitors and other large lizards (defined as those reaching over 3 feet in length) and it covers over 90 species. Lizard profiles range from the relatively affordable to the extremely expensive, and from those commonly kept as pets to those critically endangered and unobtainable. Species include iguanas (including green iguanas), rock iguanas, Galapagos Island iguanas, tegus, sail-fin lizards, Gila monsters, beaded lizards, water dragons, monitors (including savannah, water, and Nile monitors plus Komodo dragons), and more. Giant Lizards provides complete coverage of essential care subjects like feeding, housing, breeding, and health care. For the more scientifically minded reader, it includes sections o

The first, definitive reference on the natural history and ecology of every one of the known 6500+ species of lizards, spanning the entire globe. Our planet is literally crawling with lizards. More than 6500 species are known to science, and new species are being discovered annually. In this monumental work, eminent researcher Gordon Rodda has created the first compilation of the natural histories of all the world's lizards and amphisbaenians, as well as the Tuatara. Although other books have attempted to survey the scope of adaptations present in the world's lizards, only Rodda has been able to quantify and summarize all species or higher taxa. Analyzing the relationships among traits such as morphologic characteristics, reproductive strategies, and food sources, Rodda uncovers novel insights into reptile ecology. Identifying 14 recurring character syndromes across all the world's lizards, he proposes a new lens for categorization. He also touches on • common names • geographic range • length • mass • age • maturation • differences between the sexes • nominal variables, including diel activity cycle and foraging mode • home range • predator avoidance tactics • thermal biology • social spacing • climate envelope • habitat and microhabitat • reproduction • parental care • diet • population density • conservation status • ecological business models Rodda's alphabetical taxon accounts provide an instantly retrievable sketch of every species, genus, and family. Outlining more than 1500 statistically significant associations extracted from a data matrix composed of more than 300 conditions tabulated—to the extent known—for all 6528 species of lizards, Lizards of the World will be the go-to source for the next generation of reptile ecologists, as well as herpetology students and serious herpetoculturists.
