With more than 10,000 known species, recent reptiles (excluding birds) are the most specious tetrapod class. Their diversity is high, and many of them are frequently used as model organisms in phylogeographic and ecological studies. On the other hand, unique aspects of their biology are still being studied and important contributions to their understanding have just been issued. These aspects include the evolution of viviparity and of venom glands, metabolic regulation in poikilotherms, their ecophysiological tolerance and neurobiological and sensorial capacities such as infrared imaging and chemosensitivity. Genetic and developmental phenomena such as parthenogenesis and temperature-dependent sex determination are also special to reptiles. They are generally important for understanding evolutionary processes in vertebrates. The latest results of worldwide research on dinosaurs and other fossil reptiles, crocodiles and turtles conclude this first volume of Reptilia in the Handbook of Zoology.

This book presents a comparative view of chelonian reproduction and discusses ecophysiological implications for their captive breeding. Chelonians, with their protective rigid armour, are a phylogenetically antique group of reptiles which radiated to occupy niches from the open waters of the oceans, to rivers, creeks, swamps, forests, savannahs, and deserts. A few North American turtle species have been well studied, but until recently reproductive data on other chelonian species have been scarce. The way in which chelonians adjust their conservative mode of reproduction to the various requirements of their habitats and life styles is the theme of this book; the physiology of reproduction and its interplay with ecological conditions are its central subjects.

There in the shimmering green water lay four big oval shapes like a giant's carving dishes. They were patterned in brownish green and had five handles. Suddenly the handles stirred and the giant's carving dishes began to move! Chellie was very small when she first saw the beautiful green turtles with the scientific name so close to her own. Every year she would watch them swim in the sea and make their long journeys up the beach to lay their eggs. But one day, Chellie makes a grim and horrible discovery, a discovery that turns her life upside down and forces her to act.
