About Bark Centipedes: the wider group
Order-level background for Scolopendromorpha, the group containing Theatops posticus. Species-specific details appear above.
Group overview
Scolopendromorpha includes ~700 described species of tropical centipedes. The giant Amazonian centipede (Scolopendra gigantea) can reach 30cm (12 inches) and is known to catch and eat bats from cave ceilings.
Ecological role of the group
Centipedes are important nocturnal predators in tropical and temperate forests, feeding on insects, spiders, and even small vertebrates. All centipedes are venomous - they inject venom through modified front legs called forcipules.
Economic and practical significance of the group
Centipede venom is being actively researched for pain-relieving compounds. A peptide from the Chinese red-headed centipede (Scolopendra subspinipes mutilans) has shown effectiveness as a painkiller comparable to morphine in laboratory studies.
