The inland taipan (*Oxyuranus microlepidotus*), also called the fierce snake or small-scaled snake, is an extremely venomous snake endemic to arid and semi-arid regions of central Australia. It is best known for having the most toxic venom of any land snake, while living far from major human settlements.

Taxonomy and naming

The inland taipan is a species of elapid snake scientifically named *Oxyuranus microlepidotus*. Common names include fierce snake, small-scaled snake, and western taipan.

Distribution and habitat

The species occurs in remote inland Australia, especially south-western Queensland and north-eastern South Australia, in arid to semi-arid habitats such as black soil plains and Channel Country.

Venom and diet

The inland taipan is famous for having exceptionally potent venom, often described as the most toxic of any land snake. It primarily feeds on small mammals, particularly rats and mice, and its venom is adapted for mammalian prey.

Conservation and human interaction

Despite its notoriety, the species is seldom encountered because it lives far from populated areas. Available references commonly describe its conservation status as Least Concern, and no recent fatal human bites are noted in the supplied sources.

Key facts

  • The inland taipan is widely described as the world’s most venomous land snake.
  • Its venom is highly specialized for killing warm-blooded prey, especially mammals.
  • The species is native to remote inland Australia, particularly the Channel Country and surrounding arid regions.
  • It is rarely encountered by people because of its limited and remote distribution.
  • Adults are usually around 1.6 to 1.8 metres long, with larger individuals reaching about 2.5 metres.
