Ethmostigmus rubripes, commonly known as the Australian Giant Centipede, is a large species of centipede belonging to the family Scolopendridae. It is widely distributed across northern and eastern Australia, where it inhabits a range of environments including forests, woodlands, and tropical to subtropical regions. It is a primarily fossorial species, spending much of its time hidden beneath logs, rocks, leaf litter, or within shallow burrows.
This species is an active nocturnal predator, emerging at night to hunt a variety of invertebrates and small vertebrates. It uses speed, strong forcipules (venom-injecting appendages), and sensitive antennae to detect and subdue prey. Unlike ambush species, it relies on active pursuit and rapid strikes.
It is recognised by its elongated, segmented body, long antennae, and vivid reddish-orange to brownish colouration with darker banding along the segments. The legs are typically long and strong, allowing it to move quickly through soil and debris. Its appearance can vary slightly depending on locality and age.
Adults commonly reach lengths of 12–20 cm, with some individuals growing larger under optimal conditions. Females are generally more robust than males. Its large size, fast movement, and powerful predatory behaviour make it one mmof the most impressive centipedes kept in captivity.
