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).
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.
Acute kidney injury has been reported in a few cases of black mamba bites in humans as well as in animal models. [17] Death is due to suffocation resulting from paralysis of the respiratory muscles. [17] [42] Untreated black mamba bites have a mortality rate of 100%. [17] [43] Antivenom therapy is the mainstay of treatment for black mamba ...
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.
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 ...

Lachesis muta is the third longest venomous snake in the world, exceeded in length only by the king cobra and the black mamba. Weight in this species is estimated at an average of 3 to 5 kg (6.6 to 11.0 lb), somewhat less than the heaviest rattlesnakes (like the eastern diamondback rattlesnake ) or Bitis vipers (such as the Gaboon viper and ...
The evolutionary history of venomous snakes can be traced back to as far as 28 million years ago. [1] Snake venom is modified saliva used for prey immobilization and self-defense and is usually delivered through highly specialized teeth, hollow fangs, directly into the bloodstream or tissue of the target.
