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 ...
A captive juvenile king cobra in its defensive posture. The female is gravid for 50 to 59 days. [18] The king cobra is the only snake that builds a nest using dry leaf litter, starting from late March to late May. [42] Most nests are located at the base of trees, are up to 55 cm (22 in) high in the centre and 140 cm (55 in) wide at the base.
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 ...
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. Stories of black mambas that chase and attack humans are common, but in fact the snakes generally avoid contact with humans. [5]
The eastern coral snake or American cobra (Micrurus fulvius), which also does not rear upwards and produce a hood when threatened [4]: p.30 The false water cobra (Hydrodynastes gigas) is the only "cobra" species that is not a member of the Elapidae. It does not rear upwards, produces only a slight flattening of the neck when threatened, and is ...
"The Black mamba is almost as deadly as the Cobra, but the Cobra can kill people 5 times faster than the mamba" - This sentence seems highly dubious to me. It is inconsistent with the Black Mamba page and not supported by the citations that follow it, neither of which contains any direct comparison of cobra vs. mamba envenomation.
The forest cobra is Africa's largest cobra of the genus Naja [8] and possibly the largest of all the true cobra (Naja) species in the world. [7] [19] The length of an average adult is 1.4 to 2.2 m (4.6 to 7.2 ft), and they regularly attain lengths of 2.7 m (8.9 ft), [8] [20] and lengths up to 3.2 m (10 ft) have been recorded in the wild.
