Anajapygidae

Definition

A small family of diplurans (class Diplura, subphylum Hexapoda) characterized by relatively short, stout cerci that discharge abdominal secretions and by scavenging habits rather than the predatory behavior typical of most diplurans.

Etymology

Example

Unlike the long, forceps-like cerci of japygid diplurans used to capture prey, the cerci of Anajapygidae are abbreviated and function in chemical defense or communication while the animal scavenges decaying organic matter.
