The Aeolosomatidae is a family of very small, aquatic annelid worms, the affinities of which are uncertain other than that they are related to Pomatodrilus.[2] About 30 species have been described in three genera.[3] These worms are known as suction-feeding worms and occupy freshwater habitats.

Aeolosomatids feed on microalgae. They place their prostomia over the substrate and create a vacuum, swallowing small particles and their attached algae. They are hermaphrodites, but most reproduction takes place by fragmentation; the hindermost segments become detached from the parent worm and develop into new individuals.[3]
