What is the most venomous snake in the world?
List of dangerous snakes
The Inland taipan (Oxyuranus microlepidotus) is considered the most venomous snake in the world with a murine LD50 value of 0.025mg/kg SC.[6][90] Ernst and Zug et al. 1996 list a value of 0.01mg/kg SC, which makes it the most venomous snake in the world in their study too. They have an average venom yield of 44mg.[90] Bites from this species have a mortality rate of 80% if left untreated, although it is very rare for this species to bite. This species is known to be a very shy, reclusive and a laid-back snake that will nearly always slither away from disturbance. It is not an aggressive species and rarely strikes. No recorded incidents have been fatal since the advent of the monovalent (specific) antivenom therapy.
Pseudonaja nuchalis
Although the western brown snake's venom is not the most toxic in the brown snake genus, its average delivery contains a relatively high quantity of venom, and thus the western brown snake has high potential to deliver a deadly bite. Its venom contains neurotoxins, nephrotoxins, and a procoagulant, although humans are not usually affected by the neurotoxins. The bite is usually painless and difficult to see due to their small fangs. Human symptoms of a western brown snake bite are headache, nausea/vomiting, abdominal pain, severe coagulopathy, and sometimes kidney damage. In dogs and cats, paralysis is also likely to occur.
