Denisonia

Denisonia is a genus of venomous snakes belonging to the family Elapidae, commonly known as death adders. These snakes are native to Australia and New Guinea. The genus currently contains three recognized species. Denisonia snakes are characterized by their stout bodies, triangular heads, and relatively short tails. They are primarily terrestrial and inhabit a variety of environments, including forests, woodlands, and grasslands.

Species within the Denisonia genus are known for their cryptic coloration, which allows them to blend in with their surroundings, aiding in ambush predation. Their diet consists mainly of small mammals, lizards, and frogs. Despite their venomous nature, Denisonia snakes are generally considered non-aggressive unless provoked or threatened. Their venom is neurotoxic and can be dangerous to humans if a bite occurs.

The genus was first described by Albert Günther in 1872. The taxonomy of Denisonia has been subject to revision, with some species previously classified in other genera being reassigned. Conservation status varies among the species, with some facing threats from habitat loss and other environmental factors. Further research is ongoing to understand their ecology, behavior, and venom composition.
