Reptiles of Thailand
Any of a class Reptilia, are cold-blooded, air-breathing, usually egg-laying vertebrates that include crocodiles, lizards, snakes, turtles and tortoises, and that have a body typically covered with scales or bony plates and a bony skeleton with a single occipital condyle, a distinct quadrate bone usually immovably articulated with the skull, and ribs attached to the sternum
96 imagesLizards typically have four legs feet and external ears, though some are legless, while snakes lack both of these characteristics. Lizards and snakes share a movable quadrate bone, distinguishing them from the sphenodonts, which have more primitive and solid diapsid skulls. Some lizards such as chameleons have prehensile tails, assisting them in climbing among vegetation. As in other reptiles, the skin of lizards is covered in overlapping scales made of keratin.
357 imagesSnakes are elongated, legless, carnivorous reptiles of the suborder Serpentes. Like all squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws.
15 imagesTortoises and turtles are both reptiles from the order of Testudines, but in different classification families. The major difference between the two is that tortoises dwell on land, while turtles live in the water some or nearly all of the time.
