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 cobras ("Naja spp") are a medically important group of snakes due to the number of bites and fatalities they cause across their geographical range. The genus "Naja" consists of 20 to 22 species, but has undergone several taxonomic revisions in recent years, so sources vary greatly. They range throughout Africa (including some parts of the Sahara where "Naja haje" can be found), Southwest Asia, Central Asia, South Asia, East Asia, and Southeast Asia. The most recent revision, listed 28 species after the synonymisation of "Boulengerina" and "Paranaja" with "Naja". But unlike some other members of the family Elapidae (the species of the genus "Bungarus", genus "Oxyuranus", genus "Pseudohaje", and especially genus "Dendroaspis"), half of the bites by many species of both African and Asian origin of the genus "Naja" are "dry bites" (a dry bite is a bite by a venomous snake in which no venom is released). Roughly 45-50% of bites by most cobra species are dry bites and thus don't cause envenomation. Some of the species which are known and documented to deliver dry bites in a majority of cases (50% +) include: "Naja naja", "Naja kaouthia", "Naja sputatrix", "Naja siamensis", "Naja haje", "Naja annulifera", "Naja anchietae" and "Naja nigricollis". Some species will inject venom in the majority of their bites, but still deliver high number of dry bites (40-45%) include: "Naja sumatrana", "Naja melanoleuca", "Naja atra", "Naja mossambica" and "Naja katiensis". Within this genus, there are a few species in which dry bites are very rare. Envenoming occurs in at least 75-80% of bite cases involving these species. The species which typically cause envenomation in the majority of their bites include some of the more dangerous and venomous species of this genus: "Naja oxiana", "Naja philippinensis", "Naja nivea", and "Naja samarensis". There are many more species within the genus which have not yet been subject to much research and studies, and as a result, very little is known about their behaviour, venom, diet, habitat and general temperaments. Some of these species include "Naja sagittifera", "Naja annulata", "Naja christyi" and many others.
