These snakes are large enough to defend their territory from intruders, including humans. [15] The black mamba, in particular, is among the most venomous snakes in the world and one of the most aggressive. It is the longest venomous snake on the continent and is able to move at 11 kilometres per hour (6.8 mph), making it unusually dangerous. [23]
The black mamba (Dendroaspis polylepis) is a species of highly venomous snake belonging to the family Elapidae.It is native to parts of sub-Saharan Africa.First formally described by Albert Günther in 1864, it is the second-longest venomous snake after the king cobra; mature specimens generally exceed 2 m (6 ft 7 in) and commonly grow to 3 m (9.8 ft).
When the snake's prey attempts to seize it, the death adder strikes. Although it has been claimed to have the quickest strike of any snake in the world, [24] this topic has not been well enough studied to make reliable comparisons. [25] They commonly feed on local geckos such as the Dubious dtella.
Venom yield is typically 150–350 mg, with a maximum of 750 mg. [4] Brown (1973) mentions a venom yield of 180–750 mg. [17] About 100 mg (1.5 gr) are thought to be enough to kill a healthy adult human male, with death occurring after 25 hours. In humans, bites from this species can produce severe local and systemic symptoms.
A video shared online shows the scale of these 20-foot-long (6.1-meter-long) reptiles as one of the researchers, Dutch biologist Freek Vonk, swims alongside a giant 200-kilo (441-pound) specimen.
It is the heaviest venomous snake in Africa and one of the heaviest in the world along with the king cobra and eastern diamondback rattlesnake. [14] The head is large and triangular, while the neck is greatly narrowed, only about one-third the width of the head. [5] A pair of "horns" is present between the raised nostrils—tiny in B. gabonica ...
