Cobras
The best known and the most feared snakes around the world is the cobras. Thousands have been bitten each year by theses deadly snakes, and many die from the bites. A single mistake when handling these poisonous snakes and you can be going to heaven or hell right away. Most cobras strikes at their enemies with their fangs but some can spit poison at them. So if you are in Africa, or the middle east, make sure you watch out for these guys.
The two types of species of cobras are the Naja which cover most of the middle east,it is also covered with a coat of smooth scales and lay eggs. The other one is the Hemachatus has raised, somewhat buffed scales and bears live birth. Both species are ill-tempered and dangerous in the wild. All of the Hemachatus and some of the Naja are capable of "spitting" their venom or poison at an intruder, but it actually isn't spitting. What happens is that the snake raises the forward part of its body, then tilts its head and neck slightly backward. This is followed by a muscle contraction upon the two venom glands, after which the liquid toxin is ejected through an openings near the tip of each fang.
The Rinkhals Hemachatus hamachatus, venom is more diluted than that of other cobras and, for that reason, it can spray an intruder 8ft away. Should the towin, no matter how much would hit your eyes, you will feel the immanent pain. If the venom is not washed out immediately, there is a possibility of blindness. Never rub your eyes with venom present. You can wash out the venom with water, milk, or even beer but you must clean out your eyes!
Cobras can either inject lethal dosage of venom by sinking their needle-like fangs in your skin or spit out the liquid into your eyes. They are experts at doing both of them. Cobras are know to be in the sand, rivers, and trees. They can climb trees that are 20ft tall, and they cover the land from the near sea level to montane haunts at 7,500ft. They are even known to live in human territories.
So if you are wanting to go to Africa, or the middle east and see one of these beautiful yet dangerous snakes please either go around them or go back the way you come because the outcome of you being next to it will result bad. Make sure you are always on the look out for these snakes, because even if you feel like you won't get bit, you can always be wrong.

Leopard Geckos- the best pet lizard?
Leopard geckos along with the common white mouse has been bred in large amounts by animal technicians for what ever experimental purposes the men and women in white coats deem fit.
The Leopard gecko is native to western Asia. It can reach the size of 10 inches long (about half or less of which is made of the tail). It is smaller than the Tokay gecko by a few inches which is one of the largest common representatives of the geckos.The large size is one of the reasons for its popularity.
Unlike some other geckos, the leopard gecko is rounded or even slightly flattened. The head is very distinct from the neck and has broadly triangluar body shape. It has movable eyelids that can blink, while other geckos have the eyelids focused around the eyes and can not blink.
Unlike 90% of the geckos, the leopard gecko is one of a few that are active throughout the day. Which is why most of the people get these beautiful lizards, because why get a gecko when they are only active for a few hours at night where you can't see them. Throught out there early years they change alot. Mostly their colors of their skins. When they are born they are usually dark colored but when they mature throughout the year they change to brightly colors. Also leopard geckos are highly adaptive, they don't need little care just make sure you feed them, they don't need your help to breed and they can stand about any enviroment.

Artrellia: Dragon of the trees
Before westerner knew of the crocodile monitor lizard the natives of New Guinea knew of another reptile of such proportions that their largest canoes were dwarfted by its size. Heuvelmans (1995) reported that this huge animal known as the "Row" by the Kirrirri Tribe, lives near the Merauke River, among the Sterren mountains.
The "Row" is reported to be 25 feet long, has a horny flange surrounding its small head, with its body covered by irregular scales and has plates along its backbone. It is said to live in hot, humid, swampy lands similar to "The Lost World" by Sir Arthur Conan Doyle (1912). So is this lizard fact or myth?
Another mystery lizard from New Guinea is depicted in Arthur C. Clarke's " Mysterious World" (vol. III) series. In the film it shows a very large monitor lizard walking along the shoreline of the Fly River, where it enters the river and swims away. There is no additional info on the footage and the person who took it has been unproductive.

Dalton (1991) reports that along the banks of the Casurina coast of New Guinea is a lizard larger than the Komodo monitor know by the natives of that region sa the 'cuscus'. Are the Row, the Fly River Varnid, the cuscus, the Casuarine lizard and crocodile monitor the same animal? New Guinea still holds many secrets regarding this amazing lizard. Whether they are factual or mythical dosen't matter, because to the natives of New Guinea, they are real and will still be a part of the countries history.
