Cobras

April 14th, 2010

The snake called the spitting cobra is one of the most peculiar species as it not only has a venomous bite but it also sprays venom into the eyes of its prey and aggressors. Contact of this venom with your eyes can be very painful and even temporarily blinding, therefore, if you get cobra venom in your eyes, irrigate them immediately in order to prevent permanent tissue damage.

The King Cobra (Ophiophagus hannah) is also remarkable in this large family of snakes (elapidae) because it feeds almost entirely on other snakes with mice and small birds also falling prey to its poison.

The King Cobra is also a record-holder because of its size – it can reach almost twenty feet (585 cms) in length, which makes it the largest poisonous snake in the world. The most recent discovery of a new species of cobra was made in 2003 as part of an illegal shipment of exotic pets at London Zoo.

Going by DNA reports, this new species of snake is similar to the red spitting cobra but differs in genes. It apparently originates from an area between Sudan and Egypt and it has been named the ‘Nubian Spitting Cobra’.

Though highly dangerous when it is threatened cobras will not attack if you leave them alone, although the spit is very accurate for about two meters. Compared to the strike of a rattlesnake, the cobra is fairly slow in its attack and furthermore, many bites prove to be blank, that is without venom.

A study conducted on Malaysian cobra snake victims indicates that only 55% of the wounds involved venom release and the same statistics indicate a mortality rate of 10% for people bitten, since the toxins injected into the blood of the prey devastate the nerves (neurotoxin) inducing respiratory failure half an hour after being bitten, giving you 30 minutes to seek an antidote.

The colouration is variable from light green-grey to black, while juveniles are yellow and black banded. This snake can find a habitat all over south-eastern Asia.

Poisonous Florida Snakes

March 8th, 2010

Florida snakes, together with the turtles, lizards, alligators and other reptiles are part of a complicated wildlife structure that plays a marvelous role in the maintenance of Florida’s ecosystem. There are numerous species of Florida snakes. There are actually forty-four species living in unbelievably different habitats, ranging from salt marshes and fresh water marshes to dry uplands and coastal mangrove swamps to residential areas.

Only six Florida snakes are poisonous, and they happily live with their non-poisonous cousins, even venturing into towns and cities too. The best way to stay out of trouble with snakes is to care enough to learn about their morphology and therefore become able to distinguish between the Florida snakes. A relaxed attitude of avoidance is the wisest thing a person could show in relation to snakes.

The Coral snake and pit vipers are the most dangerous Florida snakes. They can be identified by a wide range of characteristics. Pit vipers include the Rattlesnake, the Cottonmouth and the Copperhead. They all have vertical eye pupils, a v-shaped head and facial pits: one between the eyes and nostrils and the others on each side of the head.

The poison of this type of Florida snakes is haemotoxic, which means that their venom attacks the red blood cells, destroying the walls of the blood vessels and causing uncontrolled bleeding. Coral snakes however, use neurotoxic venom, with the toxins in the poison acting on the body’s nerves causing paralysis.

Most of the snake bites reported every year in the United States are caused by Florida snakes or by rattlesnakes to be more precise. As their venom spreads very rapidly throughout the body, the victim will die within less than thirty minutes without immediate anti-venom.

A big exception in this group of Florida snakes is the copperheads, the venom of which rarely requires an antidote. Their toxins are the least potent and so they are considered t be the least dangerous of the poisonous Florida snakes.

It is because of the danger they present that poisonous snakes are the first kind to attract attention, however the most widespread of Florida snakes is the Black Racer, which is a non-toxic species that relies on very sharp fangs to hold onto its prey.

Although home owners usually try to remove snakes from their gardens, specialists point out that, without them, rodents would soon multiply out of control giving us an even more cause for concern.

So, unless there are any exceptional causes for worry, like snakes breeding in great numbers in your garden or shed, there is no real reason why you should upset the lives of these usually shy, useful animals.

The Copperhead

December 27th, 2009

Copperhead snakes are the snakes that cause the nastiest and most frequent snake-bite problems in the United States. The copperhead can be distinguished by its stout shape and its neck, which is distinct from the body as well as by its pale cross-band tan pattern that gets darker in the middle and on the sides.

Copperhead snakes have pale bellies, similar to the ground on which they live, but they sometimes appear pretty whitish. There are visible spots or pits on the head of copperhead snakes that look like darker tiny specks, but there is also a rather discolored stripe on the head area behind the eyes; this stripe looks very diffuse on top but it gets brownish towards the edges.

Copperhead snakes can be found almost anywhere, from rock and pond areas to woods and the shores of streams. Their choice of habitat is dictated by the predominance of prey, as copperhead snakes live on frogs, small rodents, cicadas, lizards, caterpillars and anything else that cabe taken without too much trouble.

The most usual hidey-holes for copperhead snakes, wood piles, stone slabs, walls, debris and abandoned or ruined buildings are the most common, which explains why people come across copperheads so often in such areas. The active months of the year for copperhead snakes are in the spring and summer for as long as the weather stays warm. After that they go into hibernation.

Copperhead snakes return to the same dens to hibernate year after year, and more often than not, there are large nests counting many individuals during hibernation. On very hot summer days, copperhead snakes will remain in cooler areas during the day and use the cover of the night to hunt. On balmy summer days, the copperhead will lie in the sun on rocks or wooden debris. Copperhead snakes do not hatch eggs, but give birth to their young live. The number of young ranges from one to fourteen and they are usually born from the summer untill October.

The bites of copperhead snakes must have immediate medical care since they are not only very painful but they may also lead to permanent scarring and tissue loss. Avoid copperhead snakes when you come across them, since many people get bitten when trying to kill or handle them.

Snakes will not attack you unless they feel threatened, then, you will see how fiercely they can defend themselves. Statistics reveal that copperhead snakes have the highest incidence biting in the United States, because these snakes attack immediately without giving warning signs like other species do.

Spitting Cobras

October 10th, 2009

The species of snake called the spitting cobra is very unusual as it not only has a poisonous bite but it also spits venom into the eyes of its prey and aggressors. Contact of this venom with your eyes is very painful and can even blind you temporarily, therefore, if you get cobra venom in your eyes, irrigate them with water at once in order to prevent permanent tissue damage.

The King Cobra, Ophiophagus hannah, also distinguishes itself in this large family of snakes (elapids) by the fact that it feeds almost entirely on other snakes with mice and small birds also falling prey to its venom.

The King Cobra is also unique because of its size – it can reach 5.85m (almost 20 feet) in length, which makes it the longest poisonous snake in the world. The latest discovery of a new species of cobra was made in 2003 when it was identified by London Zoo as part of an illegal shipment of exotic pets.
