Order: Archaeognatha

Represented in Australia by the family Meinertellidae, which comprises 10 species. Wingless, cylindrical body with fine scales, large compound eyes and three elongated, rear-facing tail appendages (cerci), the central cercus longer than the outer ones. Superficially similar to the silverfish (below), which have outward facing outer cerci and smaller eyes. Bristletails can jump long distances using their cerci, unlike silverfish.
