Animal Species:Giant Centipede, Ethmostigmus rubripes
This is the largest native Australian centipede and is a member of the scolopendrid family. The largest centipede in the world, Scolopendra gigantea, is a 30 cm centipede from South America that is able to eat mice and lizards.
The Giant Centipede ranges in colour from dark blue-green-brown to orange-yelllow. It has black bands along the body and yellow legs and antenna. The body is long and flatterned with 25 or 27 body segments and 21 or 23 pairs of legs. The first pair of legs behind the head are modified claws which curve around its head and can deliver venom into its prey. The venom is toxic to both mammals and insects, but does not appear to be strong enough to kill large animals quickly.
The Giant Centipede is found throughout Australia except Tasmania.
The Giant Centipede can be found in both dry and moist habitats, usually in sheltered places such as under logs,in leaf litter, soil, under rocks and bark in urban areas, forests, woodlands, heath, rainforests and deserts. It is solitary, terrestrial and a nocturnal predator.
Feeding and Diet
The Giant Centipede feed on insects, snails and worms.
Other behaviours and adaptations
Giant Centipedes are nocturnal, during the day they hide in damp, sheltered places and during the night, when the relatively humidity is high, they hunt their prey.
Mating and reproduction
Females lay their eggs in clusters, usually in summer and autumn. She guards the eggs and hatchlings till after their second moult.
Danger to humans and first aid
A Giant Centipede may bite if disturbed or handled, the bite may cause severe pain that could persist for several days. However, no deaths have been recorded from the bite of any Australian centipede. It can cause severe pain in humans which can last for several days but which can be relieved somewhat by the application of icepacks. Some people report "intense pain", while others claim it is no worse than a wasp sting.
An ice pack may relieve local pain. Seek medical attention if symptoms persist.
