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).
[17] [18] The venom of the black mamba is a protein of low molecular weight and as a result is able to spread rapidly within the bitten tissue. The venom of this species is the most rapid-acting venom of any snake species [ 19 ] [ 20 ] [ 21 ] and consists mainly of highly potent neurotoxins ; [ 22 ] [ 23 ] it also contains cardiotoxins , [ 24 ...
The black mamba (Dendroaspis polylepis) is generally considered to be one of the deadliest snakes on the planet, [2] [3] and is responsible for many fatalities throughout its sub-Saharan Africa range. Without treatment, the bite of a black mamba causes a 100% mortality rate. [4] The venom of the black mamba consists of more than 28 peptides ...
A mamba may retain the same lair for years. Resembling a cobra, the threat display of a mamba includes rearing, opening the mouth and hissing. The black mamba's mouth is black within, which renders the threat more conspicuous. A rearing mamba has a narrower yet longer hood and tends to lean well forward, instead of standing erect as a cobra does.
In addition, some species, such as the black mamba and coastal taipan, occasionally show some aggression, generally when alarmed or in self-defence, and then may deliver fatal doses of venom, resulting in high human mortality rates. [18] [19]
The second-longest venomous snake in the world is possibly the African black mamba (Dendroaspis polylepis), which can grow up to 4.5 m (15 ft). Among the genus Naja, the longest member arguably may be the forest cobra (Naja melanoleuca), which can reportedly grow up to 3 m (9.8 ft).
The coastal taipan closely resembles the African black mamba (Dendroaspis polylepis) in size, body shape, colour, venom toxicity, and hunting behaviour—both employing a "snap and release" strategy. This convergence is thought due to their adaptation to hunting mammals; the large size is needed to eat large prey, and lethal venom is to ...
Mambalgins are peptides found in the venom of the black mamba (Dendroaspis polylepis polylepis), an elapid snake.Mambalgins are members of the three-finger toxin (3FTx) protein family and have the characteristic three-finger protein fold.
