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.
Crete
There are four species of snake on the island and these are not dangerous to humans. The four species include the leopard snake (locally known as Ochendra), the Balkan whip snake (locally called Dendrogallia), the dice snake (called Nerofido in Greek), and the only venomous snake is the nocturnal cat snake which has evolved to deliver a weak venom at the back of its mouth to paralyse geckos and small lizards, and is not dangerous to humans.
