Cobra

Cobra is the common name for certain member of family of venemous snakes, known for their intimidating behavior and deadly bite. Cobra are recognized by hoods that they flare when angry or disturbed. The hoods are created by the elongate ribs that extend the loose skin of the neck behind the cobra’s head. These reptiles are found throughout the philippines, southern asia, and africa.

The king cobra is the world’s longest venemous snake. It averages 3.7 m (12 ft) in length but is know to grow to 5.5 m (18 ft). It is olive or brown color, with bronze eyes, some individual are bended. It is found in philippines, malaysia, southern china, myanmar, (formerly known as burma), india, thailand, and malay penisula. It eats primarily other snakes. The other cobra of asia is known variously as the common, asian, indian, or spectacled cobra (due to eyeglass-shaped pettern on it skin). It seldom reaches a length of more than 1.8 m (6 ft) . the hood of the common cobra is, proportionately, much larger than that of the king cobra and is usually yellow to brown, with a black and white spectacle pattern on top and two black and white spots on the lower surface. This snake causes many deaths each year on india, where it is regarded with religius awe and is seldom killed. The common cobra is frequently used by snake charmers. It ranges from the eastern shore of the caspian sea to china and malaysia.

Many species of cobras are natives of africa. Among them is the spitting, or black-necked, cobra found from south egypt to northern south africa. This snake can spray it is venom from a distance of about 2.4 (8 ft) into the eyes of it victims, causing temporary blindness and great pain. Varieties of the spitting cobra range in color from dull black to pink, the paler-colored ones marked by a black and around the neck. The ringtails, a different type of spitting cobra confined to southern africa, is one of the smallest of the cobras, reaching only about 1.2 m (4 ft) in length. It is dark brown or black with ridged, or keeled, scales and ring on the neck. The asp, or egyptian cobra, is found along the northern coast of africa.

The venom of cobras often contains a powerful neurotoxin and acts on the nervous system. With effective serum more available, however, the high death rate from cobra bites in some areas of asia has decreased. Cobra venom has been used for many yeals in medical research because it has an enzyme, lecithin’s that dissolves cell walls as well as membranes surrounding viruses.
