Coastal taipan Coastal taipan The coastal taipan ("Oxyuranus scutellatus"), or common taipan, is a species of large, extremely venomous snake in the family Elapidae. The species is native to the coastal regions of northern and eastern Australia and the island of New Guinea. According to most toxicological studies, this species is the third-most venomous land snake in the world after the Inland taipan and Eastern brown snake based on its murine . German naturalist Wilhelm Peters described the coastal taipan as "Pseudechis scutellatus" in 1867. Two subspecies are recognized as being valid, including the nominotypical subspecies. The coastal taipan is the longest
Coastal taipan being bitten, but the average is around 2.5 hours. The time between a bite and death depends on various factors such as the nature of the bite and the constitution of the victim. Untreated bites have a mortality rate of 100% as the coastal taipan always delivers a fatal dose of venom (an average bite delivers 10-12x the lethal dose of venom for a human adult male), and medical professionals recommend that victims seek immediate medical attention even for apparently minor bites. Before the introduction of specific antivenom by the Commonwealth Serum Laboratories in 1956, nearly all bites were fatal.
