Inland taipan
The inland taipan is the most venomous snake in the world. Based on the median lethal dose value in mice, its venom, drop for drop, is by far the most toxic of any snake – much more so than even sea snakes – and it has the most toxic venom of any reptile when tested on human heart cell culture. Unlike most snakes, the inland taipan is a specialist mammal hunter so its venom is specially adapted to kill warm-blooded species. It is estimated that one bite possesses enough lethality to kill at least 100 fully grown men, and, depending on the nature of the bite, it has the potential to kill someone in as little as 30 to 45 minutes if left untreated. It is an extremely fast and agile snake that can strike instantly with extreme accuracy, often striking multiple times in the same attack, and it envenoms in almost every case.
List of dangerous snakes
The Rhinoceros viper ("Bitis nasicornis") is a large species of viper that is similar to the Gaboon viper, but not as venomous, smaller and with a less dangerous bite. They are slow moving, but like other "Bitis" species, they're capable of striking quickly, forwards or sideways, without coiling first or giving a warning. Holding them by the tail is not safe; as it is somewhat prehensile, they can use it to fling themselves upwards and strike. They have been described as generally placid creatures, not as bad-tempered as the Puff adder. When approached, they often reveal their presence by hissing, said to be the loudest hiss of any African snake—almost a shriek. Relatively little is known about the toxicity and composition of the venom, but it has very minor neurotoxic, as well as hemotoxic venom, as do most other venomous snakes. The hemotoxic venom in rhinoceros vipers is much more dominant. This venom attacks the circulatory system of the snake's victim, destroying tissue and blood vessels. Internal bleeding also occurs. In mice, the intravenous is 1.1 mg/kg. The venom is supposedly slightly less toxic than those of the Puff adder and the Gaboon viper. The maximum wet venom yield is 200 mg. In only a few detailed reports of human envenomation, massive swelling, which may lead to necrosis, had been described. In 2003, a man in Dayton, Ohio, who was keeping a specimen as a pet, was bitten and subsequently died. At least one antivenom protects specifically against bites from this species: India Antiserum Africa Polyvalent.
