Which snake species is the most venomous depends on the measure used. The average or the maximum venom yield from milking could be suggested, but these measures can be criticised as not reflecting the impact of a real bite. The measure generally acknowledged as best reflecting how dangerous a snake's venom is is that of LD50. The lower this number, the less venom is required to cause death. By that measure, the most venomous snake in the world is Australia's inland taipan (Oxyuranus microlepidotus).
The animal group which most fatalities in the period from 1979 to 1998 is snakes, at 53 deaths, although if ants, bees and wasps (which are all grouped in the insect order Hymenoptera) are added together, they come very close, at 50 deaths.
