There are several kinds of reptile pets, but none is as beloved as a reptile. Reptiles are reptiles that are alive, unlike most lizards and other “non-organisms”. There are actually several different classifications of reptiles. The first main class is snakes, followed by alligators, crocodiles, and alligators.
Lizards, like most reptiles: are terrestrial, meaning they stay in one place year round. Terrestrial reptiles usually have a hardiness zone that ranges from cold to hot, depending on the species. Most lizards do not lay eggs, but some may. Alligators and turtles lay eggs, while reptiles such as snakes do not.
While the majority of reptiles remain fairly static, there are some who can easily adapt to their new environment.
- Many reptiles, such as crocodiles, have evolved to live in water.
- Many kinds of turtles have been found to be capable of moving around land.
- Many lizards have limbs that end in toes, so they may walk around on the ground.
- Although many reptiles are land-based, there are some who make their homes in the water.
Some of the more popular reptile pets: are the alligator, crocodile, and Nile crocodile. Crocodiles are primarily found in Africa and Asia, while Nile crocodiles are found in Central and Western Africa. Both lizards and snakes have been domesticated to the point where they are considered easy to care for and breed in captivity. A few selections of snakes, such as the cobra, have evolved so much that they can no longer be distinguished from other snakes. Their classification is based on what their original habitat used to be.

Many kinds of reptiles are warm-blooded: meaning that they need an internal source of heat in order to function. Although most lizards and snakes do not have this trait, certain kinds of reptiles are capable of using the cold-blooded method. These reptiles include such species as the desert iguana and the rock lizard.
Some lizards and snakes have characteristics that set them apart from amphibians. Most turtles and some snakes are covered with a hard boiled egg-laying organ called a cloaca. However, there are a select few amphibians that have both an egg-laying organ and a tail. Among the amphibians, the well-known salamanders have both the egg-laying organ and tail.
All reptiles have flexible bodies: and an assortment of appendages, including skin, claws, scales, and an exoskeleton (a hard outer shell). Certain kinds of reptiles have spines or limbs which allow them to bend or stretch without damaging their backs or legs. They also have elongated tails that enable them to swim quickly. Many reptiles have hearts that beat as a result of pumping blood through their veins. Amphibians also use their lungs to breathe.
In order to digest and metabolize their food: reptiles must keep their mouths and throats moist. All reptiles, except for dinosaurs, have gill covers, or membranes, that aid in this process. amphibians cannot breathe atmospheric air, so they must use special respiratory apparatus – lungs, stomachs, and bladders – to live in the water.
Some reptiles, such as turtles and snakes, have jointed bodies, while all others retain their two-limbed, flippers-like bodies.
