5. Taipan, coastal taipan, eastern taipan, common taipan (Oxyuranus scutellatus)
LD50: 0.99
This snake is most common on the shores of northern and eastern Australia and also in New Guinea. It prefers tropical monsoon forests and grasslands. It is Australia’s longest venomous snakes (some specimens reaching up to 3 meters!), and it also has largest fangs, around 1.3 centimeters. Being among the most venomous snakes in Australia, it also encounters people more often than its more venomous relative snake species (the inland taipan), because it feeds on mice and other rodents which dwell around urban areas.
