    Body Structure
    {internalorgans.gif} The skin of modern reptiles is covered by plates of a horny material. These scales are regularly shed and replaced, and some reptiles also have plates of bone for extra protection. A reptiles skin is hard, smooth, and dry. Reptile skin also has almost no secretory glands. They have 2 main layers of skins, the epidermis and dermis.Though snakes are often described as being "slimy," their skin is actually very dry, In fact, they only have two skin glands — a pair of scent glands that secrete a substance used to attract a mate, provide protection from predators, and mark territory. Unlike other animals, snakes continue to grow until the day they die. Consequently, snakes periodically shed their skin in a process called "ecdysis." Before shedding the skin, the snake takes on a slightly bluish hue and the eyes appear cloudy. This is caused by fluid located between the layers of skin. Mites, malnutrition, and trauma, among other things, may cause dysecdysis, or abnormal shedding.

    occipital condyles. Reptiles contain two kidneys that filter wates from the blood and excretes it in a watery fluid called urine. Reptiles also have a three chambered heart which includes one ventricle and two atria.
    The lower jaw of the reptile skull is composed of about six bones. The upper part of the reptile skull shows a number of modifications from the amphibians {turtleanatomy.jpg} skull which gives the reptile a far more efficient and powerful jaw.
    Turtles have two parts of a shell the upper part which is called the carapace and the bottom half of the shell is called the plastron. Both parts of the shell of the turtle is fused bones.The upper part of the turtle's shell has 50 bones or the ribs and the vertebrae. The bottom part of the turtle's shell has collar bone between the ribs.

    Obtaining Food
    There are different ways that reptiles obtain food for different reptile animals. Reptiles rely on their strong senses to find food and trick predators. Reptiles also have a great camouflage to try and trick their predators. Reptiles could be Carnivores or herbivores.
    ...
    Reptiles taste and smell using an organ in the top of the mouth called the Jacobson’s organ—a small cavity lined with sense detectors that recognize chemical changes in and around the mouth. This sense organ helps the animal find prey, mates, and generally get information about its surroundings.

    Reptiles have thick skin that minimizes water loss and when your in the desert you need as much water as you can get. Smaller lizards try to avoid their predators by hiding, blending in, or running away. Reptiles that have round pupils are active during the day and can probably see in color. Reptiles that have slot-like pupils are usually hunting during the night and see in black and white. Crocodiles, snakes, lizards, and turtles are all reptiles. Most reptiles live on land, and most lay eggs. .

    Few reptiles go through hibernation. They go to sleep during the hot weather. Before this time, they eat large amounts of food so that a layer of fat could form throughout their bodies. They utilize their stored fat that they obtain during the cooler season to survive.

    Alligator Facts:
    Alligators in the wild are believed to live 35 - 50 years. In captivity their lifespan may be longer, perhaps 60-80 years. Currently, there are no scientific methods getting an alligators age while it is alive. Although the tail of the alligator is considered the prime cut, all the meat of the alligator is edible.
    Alligators can run at speeds of up to 20 miles per hour. However that speed can only be used for a very short distance.
    Alligators have broad, rounded snouts and show few teeth when their jaw is closed.

    One of the main snakes is the Rattlesnake. There are about 50 species of Rattlesnakes on the Earth. Rattlesnakes eat rodents, and other small animals. The rattle is composed of a series of hollow nested beads which are modified scales from the scale tip. They mostly mate in the spring, and give live birth instead of eggs.
    Lizards are reptiles that often are four-legged with scaly skin. They have external ears and most have movable eye lids. Most lizards are good climbers or fast sprinters. They are mostly harmless to humans, but the giant lizards could pose a threat of death.

    The body of an amphibians has a small waist, no neck, and a broad flat skull. The amphibians need this body shape for swimming to make it easier. The amphibians skin is thin and moist. This allows for water to exchange. The amphibians front legs and feet are short with five toes. This is used to keep the front part of the body off the ground. The amphibians eyes are positioned on the top of their head and they are large and bulging. When the eyes are positioned at the top of the head it gives the frog a wide angled vision. The large and bulging of the eye allows the frog to see under water. The amphibians ears is shaped like a flat disk-like tympanic membrane. This prevents water from entering the ear canal. Amphibians have a layer of mucus on the outer layer of skin that helps keep water on their skin.

    Reproduction
    When frogs mate, the male frog tends to clasp the female underneath in an embrace called amplexus. He actually climbs on her back, reaches his arms around her waist, either just in front of the hind legs, just behind the front legs, or even around the head. Amplexus can last several days! Usually, it occurs in the water, though some species, like the bufos on the right mate on land or even in trees! For reproduction, most amphibians are fresh water bound.

    Amphibians are important to humans because they eat bugs. This helps us because without them our world would have way too many bugs.
