Two-pronged Bristletail
The Order (biology), order Diplura ("two-pronged bristletails") is one of three orders of non-insect hexapods within the class Entognatha (alongside Collembola (springtails) and Protura). The name "diplura", or "two tails", refers to the characteristic pair of caudal appendages or filaments at the terminal end of the body. Around 800 species of diplurans have been described. Anatomy Diplurans are typically long, with most falling between . However, some species of ''Japyx'' may reach . They have no eyes and, apart from the darkened cercus, cerci in some species, they are unpigmented. Diplurans have long antenna (biology), antennae with 10 or more bead-like segments projecting forward from the head. The abdomens of diplurans bear eversible vesicles, which seem to absorb moisture from the environment and help with the animal's water balance. The body segments themselves may display several types of setae, or scales and setae. Diplurans possess a characteristic pair of cerci pro ...
