This species is one of Africa's most feared snakes, because of its powerful venom and the speed at which it can move over the ground. It is an aggressive animal, armed with venom capable of killing humans in four hours.
Black mambas are actually grey with white bellies. The name of these snakes derives not from their body colour, but from the black area in their mouths. They are active during the day, sunning themselves in particular localities within their range, and may sometimes climb trees. Raising its head up off the ground to a height of 1.2 m (4 ft), black mouth agape, the mamba charges. Black mambas rank amongst the fastest of all snakes, capable of moving at speeds up to 20 kph (12 mph), which allows them to pursue quarry. Their potent venom causes systemic paralysis - prey die from suffocation because of respiratory failure.
Hunting by day using its excellent eyesight, black mamba usually bites its prey a couple of times and then lets go.
The stricken animal may make off but in a short time it is paralyzed by the snake's toxins, and then swallowed headfirst.

In spite of their name, these snakes are actually grey. Juveniles tend to be more olive in colour.
After biting its prey, the snake waits for the venom to take effect, although birds are generally not released after being caught.
READY TO STRIKE
A black mamba's bite can kill a person, although fatalities are rare. Their venom differs throughout their range.
Lacobson's organ, in the roof of the mouth, helps to detect scents and quarry.
