Reptiles and Amphibians are fascinating. In this area you will find Alligator photos, Crocodile photos, Frog photos, turtle photos, tortoise photos, snake photos, and lizard photos as well as photo gifts.

Reptiles are animals in the (Linnaean) class Reptilia characterized by breathing air, a "cold-blooded" (poikilothermic) metabolism, laying tough-shelled amniotic eggs (or retaining the same membrane system in species with live birth), and skin with scales or scutes. They are tetrapods (either having four limbs or being descended from four-limbed ancestors) and lay amniotic eggs, in which the embryo is surrounded by a membrane called the amnion. Modern reptiles inhabit every continent with the exception of Antarctica, and four living orders are currently recognized: Crocodilia (crocodiles, gavials, caimans, and alligators), Sphenodontia (tuataras from New Zealand), Squamata (lizards, snakes, and worm lizards), and Testudines (turtles and tortoises).

The majority of reptile species are oviparous (egg-laying), although certain species of squamates are capable of giving live birth. This is achieved by either ovoviviparity (egg retention) or viviparity (birth of offspring without the development of calcified eggs). The science dealing with reptiles is called herpetology.

Amphibians (class Amphibia, from Amphi- meaning "on both sides" and -bios meaning "life"), such as frogs, toads, salamanders, newts, and caecilians, are ectothermic (or cold-blooded) animals that metamorphose from a juvenile water-breathing form, either to an adult air-breathing form, or to a paedomorph that retains some juvenile characteristics. Proteidae (mudpuppies and waterdogs) are good examples of paedomorphic species. Though amphibians typically have four limbs, the caecilians are notable for being limbless. Unlike other land vertebrates (amniotes), most amphibians lay eggs in water. Amphibians are superficially similar to reptiles. Amphibians are ecological indicators, and in recent decades there has been a dramatic decline in amphibian populations around the globe. Many species are now threatened or extinct.
