The name comes from Greek: caeno- (καινός (caenos) = new, recent); rhabditis = rod-like (ῥάβδος (rhabdos) = rod, wand).
Juvenile worms and also dauer larvae can be transported by invertebrates including millipedes, insects, isopods, and gastropods.
A necromenic worm waits for the host to die, and lives on the bacteria which thrive in the dead animal.
