Opheliidae is a family of small, annelid worms. Some of the genera, like Armandia, Ophelina and Polyophthalmus, have lost their circular muscles.Annelida, by Greg Rouse, Fredrik Pleijel, Ekin Tilic The Opheliidae family of polychaete; marine annelid worms,Merriam-Webster Dictionary.

Worms in the Opheliidae family generally show characteristics of having a smooth body, a ventral (front) crease, few flaps on their sides and a pointed head to help them travel through mud and sand. Overall they specialize in burrowing and consuming sediment particles.Parapar, J., Martínez, A., & Moreira, J. (2021). On the Systematics and Biodiversity of the Opheliidae and Scalibregmatidae.
