Onuphidae

The Onuphidae are a family of polychaete worms.

==Characteristics== Most onuphids have tubes. Some live semisubmerged in the substrate, but others carry their tubes around, and they can all rebuild their tubes if necessary. The tubes, thin and parchment-like, are formed of bits of shell and sand, with plant debris, stuck together with mucus. The onuphids are all omnivorous scavengers, feeding on animal and vegetable debris.
