What is the most venomous snake in the world?

The Inland Taipan (Oxyuranus microlepidotus), also commonly known as the western taipan, the small-scaled snake, or the fierce snake,is an extremely venomous snake of the taipan(Oxyuranus) genus, and is endemic to semi-arid regions of central east Australia. Aboriginal Australians living in those regions named the snake Dandarabilla. It was first described by Frederick McCoy in 1879 and then by William John Macleay in 1882, but for the next 90 years, it was a mystery species to the scientific community. No more specimens were found, and virtually nothing was added to the knowledge of this species until its rediscovery in 1972.

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. It has the most toxic venom of any reptile when tested on human heart cell culture. It is estimated that one bite possesses enough lethality to kill at least 100 fully grown men, 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, although extremely venomous and a capable striker, in contrast to the rather aggressive coastal Taipan, the Inland Taipan is quite a shy and reclusive snake, however, it will defend itself and strike if provoked.
