Transcript of The Reptiles by Guille 5º A
CHARACTERISTICS OF REPTILES Most reptiles live in a tropical rain forest , in the water or in
the desert. Synoptic topics cover different aspects as biotopes, activity
patterns, physiological adaptations, food chains and webs, communities of amphibians and reptiles, or zoogeographic aspects.
In a series of north-south-transects through the countries of the region hundreds of data on the local distribution of species are summed up and give an overview of the regional herpetofaunas
THE REPTILES Reptiles, are an evolutionary grade of animals, comprising
todays turtles, crocodilians, snakes, lizards, and tuatara, as well as many extinct groups. A reptile is any amniotes (a tetrapod whose egg has an additional membrane, originally to allow them to lay eggs on land) that is neither a mammal nor a bird. Unlike mammals, birds, and certain extinct reptiles, living reptiles have scales or scutes (rather than fur or feathers) and are cold-blooded.
THE SNAKES Snakes are elongated, legless, carnivorous reptiles of the
suborder Serpents that can be distinguished from legless lizards by their lack of eyelids and external ears. Like al squamates, snakes are ectothermic, amniotes vertebrates covered in overlapping scales. Many species of snakes have skulls with many more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws.
THE LIZARDS Lizards are a widespread group of squamate reptiles, with
approximately 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group, traditionally recognized as the suborder Lacertilian, is defined as all extant members of the Lepidosauria (reptiles with overlapping scales) that are neither sphenodonts (i.e., tuatara) nor snakes they form an evolutionary grade.
THE CROCODRILES Crocodiles subfamily Crocodilian) or true crocodiles are
large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodilian, in which all its members are considered true crocodiles, is classified as a biological subfamily.
THE TURTLES Turtles are reptile of the order Cheloni or Testudines
characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield. Turtle may refer to the chelonian order as a whole (American English) or to fresh-water and sea-dwelling chelonians (British English).
