Gaboon Viper Photograph by Michael Nichols A close-up shows the watchful eye of a Gaboon viper, Africa's largest viper. These highly venomous snakes can reach six feet (two meters) long and weigh 40 pounds (20 kilograms). Their fangs are the longest of any poisonous snake on Earth, growing up to two inches (five centimeters) long.
The Carpet Viper causes most of the snakebite deaths worldwide. Its poison can keep the victim’s blood from coagulating, and the person can bleed to death.
A two-headed albino Honduran milk snake is shown in Ridge Manor, Florida. Snake of this species are normally orange and black. Daniel Parker, a University of Central Florida biologist, says two-headed snakes have been documented to live as long as 20 years in captivity. But with two brains giving commands to a single body, Parker says the snake would have a difficult time surviving in the wild.
