First of I extend my gratitude to reptile expert George Van Horn and his wife Rosa for their participation in this program. Their generous help, knowledge and wisdom made it possible to shine a light into the life of cobras and many other venomous sankes.
The highest rate of snakebite fatalities by far occurs in south Asia, particularly on the Indian subcontinent, where nearly 11,000 deaths occur every year, with the majority of snake bites attributed to cobras. Poor, rural areas that lack appropriate medical care and the correct anti venom contribute to this high number of snakebite fatalities. Cobras belong to the family of the Elapidae, along with mambas, kraits and coral snakes. The genus Naja contains over 20 species of cobras and is the most widespread and recognized genus of cobras. Members of the genus range from Africa through the Middle East, India, and Southeast Asia to Indonesia. Cobras very rarely attack people unprovoked, but when disturbed, they make full use of their deadly venom. Young cobras have the same amount of venom as the adult ones. Cobras prey on other snakes, birds and small mammals, while its main natural predators are other snakes, birds of prey and mongooses. Bad Bites of cobras was filmed by Heiko Kiera aka Ojatro in Florida in 2013.

First of I extend my gratitude to reptile expert Jack Facente for his participation in this program. His generous help, knowledge and wisdom made it possible to shine a light into the life of these reclusive yet wonderful animals. Coral snakes are extremely venomous, yet very secretive snakes, belonging to the family of elapids, which includes cobras, mambas and kraits. They are most notable for their red, yellow to white, and black colored banding. Coral snakes are native to North America such as the eastern or common coral snake, the Texas coral snake and the Arizona coral snake, found in the southern and western United States. Coral snakes can be found in other parts of the world which can have distinctly different patterns. Most species of coral snake are small in size. The North American species average around 3 feet (91 cm) in length, but specimens of up to 5 feet (150 cm) or slightly larger have been reported. Aquatic species have flattened tails acting as a fin, aiding in swimming.
Statistically, about 8,000 people are bitten by venomous snakes in the United States each year and an average of 10 people a year die because of improper care. In the Florida, about 10 people per year were bitten by a cottonmouths aka water moccasins near water. The height of snake season is between April and October, peaking between July and August. Snakes are generally less active at temperatures less than 50-60 degrees, or greater than 80 degrees. The cardinal signs and symptoms of pit viper envenomation include: burning pain (the commonest, earliest sign), puncture wound (50% of the time accompanied by a bloody ooze), swelling, skin discoloration, nausea and vomiting, minty, metallic, rubbery taste in the mouth, sweating, chills, numbness and tingling of the mouth, face, scalp, and wound site, ecchymosis and production of blebs and blisters, erythema and edema progressing from the wound site, weakness, vertigo, haematemesis epistaxis, muscle fasiculations, paralysis, shock, convulsions, loss of sphincter control, melena haematuria, and renal shutdown. Envenomation may include some or all of these symptoms, depending on the severity of envenomation. Death can occur up to several days following the bite, or in as little as two hours. In pit viper envenomation the average death occurs in two days. If the bite is inflicted in an artery, vein, lymphatics, or a nerve, death will occur in 30 seconds to 10 minutes. If the victim does not die within the first 10 to 30 minutes, you have excess of 12 hours to get to proper medical help; in most cases, severe complications or death will not occur if proper medical protocol is followed.

The Egyptian cobra (Naja haje) is a species in the genus Naja found in Africa and the Arabian Peninsula. It is one of the largest Naja species in Africa. The Egyptian Cobra occurs in a wide variety of habitats like, steppes, dry to moist savannas, arid semi-desert regions with some water and vegetation. It ranges across most of North Africa north of the Sahara, across the savannas of West Africa to the south of the Sahara, south to the Congo basin and east to Kenya and Tanzania, and in southern parts of the Arabian Peninsula.
The Egyptian cobra is terrestrial and nocturnal species. It can however, be seen basking in the sun at times in the early morning. This species shows a preference for a permanent home base in abandoned animal burrows, termite mounds or rock outcrops. It is an active forager sometimes entering human habitations, especially when hunting domestic fowl. Like other cobra species, it generally attempts to escape when approached, but if threatened it assumes the typical upright posture with the hood expanded. The Egyptian cobra is an especially aggressive species.
The venom of the Egyptian cobra consists mainly of neurotoxins and cytotoxins. The venom affects the nervous system, stopping the nerve signals from being transmitted to the muscles and at later stages stopping those transmitted to the heart and lungs as well, causing death due to complete respiratory failure.
This cobra species prefers to eat toads, but it will prey on small mammals, birds, eggs, lizards and other snakes. The hatching of Egyptian Cobras was filmed by Heiko Kiera aka Ojatro in 2012

July 2012: I’ve jointed wildlife biologist Joe Wasilewski and reptile expert Tom Cruchfield to rise awareness for their rock iguana conservation project. All Bahamian Iguanas are critically endangered today. Some species counting less than 500 animals, like the rock iguanas found on the island of San Salvador, making them the rarest lizard on earth. This wonderful animals need our help to survive. Please get involve by spreading the word and sharing this video. Your help will be much appreciate.

The cottonmouth (aka water moccasin) is immune to it's own venom. These opportunistic feeders are know to feed on snakes, including their own species as well as other venomous snakes such as the eastern diamondback rattlesnake shown in this video. The cottonmouth's bite injected a fair amount of venom into the rattler's head, which subsequently swelled considerably and paralyzed the rattlesnake within thirty minutes. Nevertheless, it can be observed from this footage, that the eastern diamondback rattlesnake was still alive (tail movements) while almost swallowed by its predator...
