Convolutidae is a family of Acoela. It contains more than a third of all known acoel species.[1]

Systematics

Currently the family contains 13 genera, the type genus being Convoluta.[2]

The genus Waminoa appears, according to recent studies also belong to the family, or is at least closely related.[3]

Characteristics

The family Convolutidae includes acoels with a ventral mouth opening and a body-wall musculature composed both dorsally and ventrally by circular, longitudinal, and longitudinal crossover muscle fibers. The ventral body wall also has a group of U-shaped fibers.[1]

Most species are symbionts with algae.[1]
