COBRAS

          Cobras are famous for the threatening hood at their neck. They spread the hood out when they feel threatened or angry. Their hood is made up of flaps of skin attached to long ribs. They are also able to lift their heads high up off the ground, which is not only kinda scary, but helps them to search for food. And just to make them a little scarier, they hiss loudly to scare off potential predators.

There are 270 different types of Cobras and they all have short fangs and are all extremely poisonous.

          Cobras live in hot tropical areas in Africa, Australia, and Southern Asia They can be found underground, in trees, and under rocks. The King Cobra is not only an excellent climber but a super swimmer as well. They live in forests near streams.

        These snakes are hunters and will quietly follow their prey until they are ready to attack. They can move very fast and can speed along with their heads raised. Cobras are cannibals, which means that they will eat other snakes as well as birds, bird eggs and small mammals. Kraits feed almost totally on other snakes.

         Cobras lay eggs and will stick around to defend them until they hatch. Wild boars and mongooses will steal cobra eggs. A mongoose will often win fights with Cobras because of their speed and agility. They also have thick fur to protect them against the cobra’s fangs.

SPITTING COBRA :

          Spitting cobra refers to any one of several species of cobras. They are venomous snakes of family Elapidae of several genera that has the ability to spit or eject venom or zootoxin is any of a variety of poison used by several groups of animal species from their mouth when defending themselves against predators. The spit venom, although not generally fatal on contact, can cause permanent blindness if introduced to the eye, and skin scarring if left untreated. Despite their name, these snakes don't actually spit their venom. They rather spray the venom, using muscular contractions upon the venom glands. The muscles squeeze the glands to forcefully propel the venom out of front openings in the fangs. To further aid this, the two streams of venom from each fang cross each other soon after leaving the snake, adding velocity to the combined stream.

EGYPTIAN COBRA :

            The Egyptian cobra is a type of venomous reptile whose venom or zootoxin is any of a variety of poison used by several groups of animal species snake native to North Africa North Africa or Northern Africa is the northernmost region of the Africa continent and the Middle East Middle East. The Middle East is a subcontinent for the historical and cultural. The Egyptian Cobra is the most common cobra in Africa and has caused the most deaths. It lives from the Sahara Desert Sahara which is the world's largest hot desert and second largest desert at over 9,000,000 km to the Syrian Desert. The Egyptian Cobra, like all other cobras, raises its hood when in danger. It is also the largest of all cobra species with a maximum length of 300cm.

KING COBRA :

          The King Cobra is the longest of the venomous land snake, growing up to 18.5 feet in length, which is the largest of the venomous snakes. The King Cobra is found in a different genus and is therefore not a true cobra like the Egyptian Cobra.

INDIAN COBRA :

             The Indian Cobra or Spectacled Cobra is a species of venomous Snake, also known as ophidians, are cold-blooded legless reptile closely related to king cobras. As suggested by their names, they are commonly belonged to India and are commonly observed to be worshipped and treated as gods. They are also painted on their worship areas and buildings.

BLACK COBRAS :


       The black or spectacled cobra is a medium-sized, heavy snake; head not distinct from neck which is dilatable in life into a broad hood; single fang on each side, followed by 1-3 small solid teeth; scales smooth shiny, in 21-23 at midbody; ventral. Single pair of prefrontals, absence of loreal scale and smooth dorsals.

Their color varies from jet black, dark olive or dark brown dorsum, with heavy slate gray or dark brown clouding. A spectacle mark on hood dorsum, and a ventral large ocellus, consisting of an outer yellow ring with central dark eye, mesially interrupted by ventrals, some are dark clouded. Variegated specimens with light-edged light brown scales are met with in Punjab, while jet black are very rare. Juvenile has speckled or uniform dorsal pattern. Snout-vent length 1658 mm, tail 269 mm. The Central Asian or Brown cobra has ventrals 191-210, subcaudals 62-71; single maxillary tooth (fang) on each side; juvenile pattern conspicuously banded, bands around the body. Light yellowish to light brown, with or without a hoodmark. Some ventrals underhood dark. Ventrum clouded with black. Snout-vent length 1370-1512 mm, tail 228-236 mm. This cobra is diurnal; mostly active during evening and early morning. It may enter human dwellings when hunting. It restlessly moves from place to place in search of prey, which mainly consists of mice, rats, poultry, frogs and snakes. Normaly, it is not considered aggressive, particularly shy of human beings and will avoid confrontation. Habitually it avoids confrontation with man, at a chance en-counter, first priority is to escape undetected. On sensing danger it lifts anterior part of its body to have a good look at its surroundings. If not provoked, it lets fall its body and slips quietly away. However, if provoked, it hisses loudly and sways its hood to advertise its presence, and displays the hood markings to impress its adversary. It fixes its eyes to the source or annoyance, keenly following its movements. However, all the time at the lookout to have a chance to avoid conrontation and slip away. The swaying of hood with dorsal spectacle mark and ventral yellow ocellus, coupled with loud hiss, arc measures to just look as fearsome and as big as possible, to impress the enemy. Cobra attacks viciously and furiously, striking with full strength and biting savagely, chewing the bitten pan. When bitting, it hold on and chews savagely. May strike repeatedly. This snake can be exceptionally quick-moving and agile. The fangs and venom glands of both subspecies are large. The venom is highly toxic. Snake bite symptoms begin approximately 8 minutes after bite. Victims experiences anxiety, the pulse quickens, grows weak and irregular. The victim soon falls into deep coma.
