<P> The Many - banded krait (Bungarus multicinctus) is the most venomous krait species known based on toxinological studies conducted on mice . The venom of the many - banded krait consists of both pre - and postsynaptic neurotoxins (known as α - bungarotoxins and β - bungarotoxins, among others). Due to poor response to antivenom therapy, mortality rates are very high in cases of envenomation - up to 50% of cases that receive antivenom are fatal . Case fatality rates of the many - banded krait envenoming reach up to 77%--100% without treatment . The average venom yield from specimens kept on snake farms was between 4.6--18.4 mg per bite . In another study, the average venom yield was 11 mg (Sawai, 1976). The venom is possibly the most toxic of any Bungarus (krait) species and possibly the most toxic of any snake species in Asia, with LD values of 0.09 mg / kg--0.108 mg / kg SC, 0.113 mg / kg IV and 0.08 mg / kg IP on mice . Based on several LD studies, the many - banded krait is among the most venomous land snakes in the world . The Taiwan National Poison Control Center reports that the chief cause of deaths from snakebites during the decade (2002 - 2012) was respiratory failure, 80% of which was caused by bites from the many - banded krait . </P> <P> The Malayan krait (Bungarus candidus) is another dangerously venomous species of krait . In mice, the IV LD for this species is 0.1 mg / kg . Envenomation rate among this species is very high and the untreated mortality is 70%, although even with antivenom and mechanical ventilation the mortality rate is at 50% . </P> <P> The Inland taipan (Oxyuranus microlepidotus) is considered the most venomous snake in the world with a murine LD value of 0.025 mg / kg SC . Ernst and Zug et al. 1996 list a value of 0.01 mg / kg SC, which makes it the most venomous snake in the world in their study too . They have an average venom yield of 44 mg . 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 . </P> <P> The Eastern brown snake (Pseudonaja textilis) has a venom LD value of 0.053 mg SC according to (Brown, 1973) and a value of 0.0365 mg SC according to (Ernst and Zug et al. 1996). According to both studies, it is the second most venomous snake in the world . Average venom yield is 2--6 mg according to (Meier and White, 1995). According to (Minton, 1974) average venom yield (dry weight) is between 5--10 mg . Maximum venom yield for this species is 155 mg . This species is legendary for its bad temper, aggression, and for its speed . This species is responsible for more deaths every year in Australia than any other group of snakes . </P>
