[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 ...
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.

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.
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.
