Cobra Bites Are Fatal In About 10% Of Human Cases


This guy literally has one of the world's most dangerous jobs, he has to clean the cobra pit at the zoo. In this video he fearlessly picks up the snakes from their napping spots and tosses them to the side like their rubber toys and sweeps up their dried egg shells and poop.

The Black Mamba (Dendroaspis polylepis) is one of Africa's most dangerous snakes and feared in East, Central and Southern Africa. It's aggressive when cornered and will not hesitate to strike. It can reach speeds of up to 12 mph (20 km/ph). It's the largest venomous snake in Africa with adults reaching an average of 8 feet in length (2.5m). Black Mamba's are not black at all, but brown/olive skinned. Their mouths are inky black which they show when threatened. Black Mambas live in savanna, scrub, tree hollows, and sometimes people's homes. If a Black Mamba encounters prey it can strike up to 12 times, each time delivering enough neuro and cardio-toxic venom to kill a dozen men within 1 hour. Without anti-venom, the mortality rate is 100%.

Cobra bites are fatal in about 10% of human cases. it's because of their VENOM that acts as a defense mechanism and also a way by having their pray or food be caught.

Any of several highly venomous Elapids snakes that expand their neck ribs to form a hood. They are found in warm regions of Africa, Australia, and Asia. Cobras feed primarily on small vertebrates. The Indian cobra (Naja naja) kills several thousand people annually, mostly because it enters houses to catch rats. The king cobra (Ophiophagus hannah) is the world's largest venomous snake, often more than 12 ft (3.5 m) long. Some African cobras can spit their venom more than 6 ft (1.8 m). Cobras are favourites of snake charmers, who, by their movements rather than their music, tease the deaf snakes into assuming the upreared defense posture.

The Cape Cobra (Naja nivea) has a powerful venom and is one of the deadliest snakes in Southern Africa. Cape Cobras grow to an average of around 4 feet. Cape Cobras are particularly dangerous because they tend to be nervous and aggressive. Without treatment, the mortality rate in humans is 60% and death normally occurs 2-5 hours after being bitten, usually as a result of respiratory failure due to the onset of paralysis. The Cape Cobra is a beautiful looking snake some are yellow, some copper/mahogany colored and some are purplish/black. The Cape Cobra loves to hunt for rodents and can climb trees to raid weaver bird colonies. The Cape Cobra is common throughout dry regions in Southern Africa.

A Nightingale Is A Poet Who Sings In Darkness To Cheer The Solitude

nightingale
Apart from its habitat, dietary habits, temperament and life span, you might not know much about a nightingale. In fact, there are a few facts about them that you might not have heard about:
   
* The term nightingale stands for "night songstress". According to this, one might assume that it is the female bird that sings. However, in reality, it is the opposite. The high-pitched melodious voice is actually of the male.

* At the time of when the egg hatches, a male nightingale will stop singing. It does this in order to avoid gaining any attention towards itself and its kids. However, it may whisper little chirps to the female to let it know of their safety or any potential danger.

* It is very difficult to differentiate a male nightingale from a female. This is because the differences in between them are too slight to be noticeable. The male has slightly a yellowish, brown upper part, goes reddish near the head, and goes even darker around the main feathers. As for the lower part, it has a gray-white streak which extends till the tail. The female, on the other hand, is a little smaller in size. However, it has the same colors of the feathers. Moreover, it does not stand as straight as the male, and has smaller eyes than the male.

They are a road map that point you in the right direction. Each message is filled with instruction, right down to the very last detail, providing you with insights and ways on how to escape from your current state of misery.

You can change all this if you decide to visit the Cotswold Water Park for a Cotswold break towards the end of April. On Wednesday 28th April there will be a special event in the park which will bring you closer to the lesser spotted nightingale.

The event is called the Nightingale Symphony, which should go a long way towards telling you what to expect on the night. The event starts at half past seven in the evening, so you will have all day to enjoy the delights of the Cotswolds before going along to enjoy this event. The Cotswold Water Park website states that advance booking is necessary, since only a small number of people will be able to attend. This makes sense as too many people could frighten the birds off and make it impossible to hear them sing.

The nightingale is slightly larger than the European Robin, at 15–16.5 cm (5.9–6.5 in) length. It is plain brown above except for the reddish tail. It is buff to white below. Sexes are similar. The eastern subspecies L. m. hafizi and L. m. africana have paler upperparts and a stronger face-pattern, including a pale supercilium.

Nightingales are named so because they frequently sing at night as well as during the day. The name has been used for well over 1,000 years, being highly recognizable even in its Anglo-Saxon form – 'nightingale'. It means 'night songstress'. Early writers assumed the female sang when it is in fact the male. The song is loud, with an impressive range of whistles, trills and gurgles. Its song is particularly noticeable at night because few other birds are singing. This is why its name includes "night" in several languages. Only unpaired males sing regularly at night, and nocturnal song is likely to serve to attract a mate. Singing at dawn, during the hour before sunrise, is assumed to be important in defending the bird's territory. Nightingales sing even more loudly in urban or near-urban environments, in order to overcome the background noise. The most characteristic feature of the song is a loud whistling crescendo, absent from the song of Thrush Nightingale. It has a frog-like alarm call.

During the Romantic era the bird's symbolism changed once more: poets viewed the nightingale not only as a poet in his own right, but as “master of a superior art that could inspire the human poet”. For some romantic poets, the nightingale even began to take on qualities of the muse. Coleridge and Wordsworth saw the nightingale more as an instance of natural poetic creation: the nightingale became a voice of nature. John Keats' "Ode to a Nightingale" pictures the nightingale as an idealized poet who has achieved the poetry that Keats longs to write. Invoking a similar conception of the nightingale, Shelley wrote in his “A Defense of Poetry".

"A poet is a nightingale who sits in darkness and sings to cheer its own solitude with sweet sounds; his auditors are as men entranced by the melody of an unseen musician, who feel that they are moved and softened, yet know not whence or why."
