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.

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 Monitor Lizard is large; adults can grow up to 7 feet in length. A vicious predator that will eat anything it can fit into its mouth. Native to Africa, the Monitor Lizard has successfully established a new home in Florida, disrupting an already delicate ecosystem.

Monitor lizards are some of the most exciting captives that reptile enthusiasts can keep. They are always the center of attention at zoos and pet stores, where their dinosaur-like form captivates and entertains adults and children alike. While many species are inappropriate pets for all but the most experienced keepers, several of the smaller species make wonderful captives. Nevertheless, even the smallest species require relatively large cages and inordinate amounts of food, so keepers must consider the acquisition of a monitor lizard carefully. For those that choose to add a monitor lizard to their family, it is imperative to learn about the biology, natural history and habitats of these remarkable lizards. By doing so, you can gain a better understanding of their needs, allowing you to keep your pet happy and healthy for many years. Topics covered in this book: - Anatomy - Biology - Behavior - Taxonomy - Costs - Acquiring - Captive Habitat - Enclosures - Heating - Lighting - Temperature - Maintenance - Feeding - Hydration - Interaction - Health Problems - Breeding - Good pet species ----- and much more

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.

A lonely boy’s new pet grows into a rather large dilemma—and a Thanksgiving parade offers an uplifting solution—in this charming tale from the author of The Boy and the Airplane and The Girl and the Bicycle.

Leonard names his new pet Buster and takes him all around the city: on the subway, to the library, to a baseball game, and more. But Buster keeps growing and growing—and Leonard gets the sense that Buster is longing for something Leonard can’t provide.
