Reptiles

By: Aaron Walton

What class are they?

Reptiles are of the reptilia class. They are neither birds nor mammals. They are commonly confused with amphibians.

Reproduction

Reptiles reproduce by laying eggs. They guard their eggs, and sometimes bury them.

Movement

Reptiles move by either slithering along the ground like a snake, or they can walk on four legs. Some move quickly like lizards, and others don't such as crocodiles.

Where do they live?

Reptiles live mainly on land. Most of them can also live in the water, but prefer land. They typically live anywhere that its warm, or hot.

Body Parts

All reptiles breath using lungs. Some have permeable skin, but breathing can never be done without lungs. Reptiles must hold their breath while swallowing. Most reptiles have skin that is horny, and waterproof, or at least water tight. Most reptiles have a very short digestion time. Excretion is performed mainly by two small kidneys.

Who studies reptiles?

Herpatologist are scientist that study reptiles, and sometimes amphibians. They study things such as behavior, and the habitat in which the animals live.

Adaptations

Reptiles have adapted to their environment by being able to camouflage with their surroundings. They can shed their skin, so they always have a new coat of skin, and all reptiles have a different way of defending themselves.

Species

Five species of reptiles are, crocodiles, alligators, geckoes, turtles, and snakes.

How long have they been around?

Reptiles have been around since the prehistoric days. Scientist say that reptiles, and birds were very much alike in body structure, and behavior. Reptiles are of course still alive today.
