The newly anointed Ashe's spitting cobra, or large brown spitting cobra (Naja ashei), can reach lengths of more than 9 feet (274 centimeters) and is believed to deliver more venom with a single bite than any other cobra on the planet.
The aggressive reptile was previously identified as a brown-colored variant of the black-necked spitting cobra, though researchers had long suspected that it merited its own species. Now blood and tissue analysis have confirmed this theory to be true.
The snake dwells in the dry lowlands of north and east
The findings were first published earlier this year in the animal taxonomy magazine Zootaxa by researchers at the
But they gained wider notice on Friday when the researchers announced the new species through the nonprofit conservation group WildlifeDirect.
Spitting cobras eat eggs, carrion, snakes, lizards, and birds. Their venom has two uses: to kill prey and for defense. The reptiles can spray venom several yards and usually aim for the attacker's eyes, giving the snake the best chance for escape.
A Healthy Appetite
Snake experts had long believed that the brown spitting cobra was fundamentally different from the black-necked spitting cobra. Other variants of the black-necked spitting cobra fought harder when handled and took longer to settle down in captivity. Once in their cages, they were picky eaters. But the Ashe's cobra was less resistant to handling, generally less alert, and less picky. And they were bigger. Ashe's cobras are not the only kinds of snakes that get lumped together.
Researchers suspect that many different species of snake, such as the highly venomous puff adders, have been grouped into species that need greater differentiation.
Ineffective Antivenin
The greatest significance of the new finding may be for residents along
That means that doctors previously treating bites from what turned out to be Ashe's cobras were only administering half the necessary dose of antivenin to victims. New developments in antivenin may be made from studying the chemical makeup of the new cobra's venom, researchers add.
"The fact that this is a separate species raises a question of the efficacy of existing antivenins," said David Warrell, a herpetologist at the
"It hasn't been studied at all, so that's a complete mystery."
