Conservation
Least Concern (IUCN), though localized declines occur due to habitat loss and the impact of invasive Cane Toads (Rhinella marina).
Physical Description
Short, thick-set body with a broad, triangular head. Eyes have vertical pupils. Scales are slightly keeled. Coloration is typically grey to reddish-brown with darker crossbands; the tail terminates in a thin, worm-like lure.
Size & Dimensions
Specimen appears to be an adult (approx. 50-70 cm). Species average is 50-60 cm, with maximums reaching around 100 cm.
Habitat
Found in forests, woodlands, and grasslands. They prefer areas with deep leaf litter or low-growing vegetation for camouflage; ranges from sea level to mountainous regions.
Diet & Feeding
Small mammals, birds, and lizards. Uses 'caudal luring,' twitching its worm-like tail tip to attract prey within striking range.
Reproduction
Viviparous (gives birth to live young). Typical litter size is 10 to 30 young, born in late summer.
Look-alikes
Often confused with vipers (Viperidae) due to convergent evolution in body shape. Distinguishable from many other Australian snakes by its extremely fast strike and uniquely thin tail tip.
Conservation Status
Least Concern (IUCN), though localized declines occur due to habitat loss and the impact of invasive Cane Toads (Rhinella marina).
Cultural Significance
Fascinating example of convergent evolution, where an elapid has evolved to occupy the ecological niche typically held by vipers in other parts of the world.
Notable Features
Possesses one of the fastest strikes in the world. Its tail features a modified tip specifically for luring prey, and its dorsal scales help it blend perfectly into soil and litter.
