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 Samar cobra ("Naja samarensis") is a highly venomous species of spitting cobra that is found in the southern islands of the Philippines. Although it is a spitting cobra, this species only rarely spits its venom. It is considered to be an extremely aggressive snake that strikes with little provocation. The venom of this species is not well studied, but is known to be an extremely potent postsynaptic neurotoxin that also contains cytotoxic agents. According to Ernst & Zug et al. the murine SC value is 0.21 mg/kg, making it one of the most venomous true cobra species (genus "Naja") in the world. Severe envenomation is likely in case of a bite and envenomation rate is high. The untreated mortality rate is not known, but is thought to be high (~60%). Envenomation results in marked local effects such as pain, severe swelling, bruising, blistering, and necrosis. Other effects include headache, nausea, vomiting, abdominal pain, diarrhea, dizziness, collapse or convulsions. There may also be moderate to severe flaccid paralysis and renal damage. Cardiotoxicity is possible, but rare.
