Convolutidae is a family of acoels, belonging to the phylum Xenacoelomorpha. This family contains more than a third of all known acoel species. [2] [3]
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. [2] Most species are symbionts with algae. [2] The anterior end has a cluster of frontal glands, a pair of eyes and a statocyst. The body has pigmented lens. Intestine and excretory system is absent. It is hermaphrodite but protandry is common.
There are 26 genera in the family Convolutidae, of which 25 are extant. [4] [5] The type genus is Convoluta.
There are over 100 species recognised in the family Convolutidae: [4]

Acoela, or the acoels, is an order of small and simple invertebrates in the subphylum Acoelomorpha of phylum Xenacoelomorpha, a deep branching bilaterian group of animals, which resemble flatworms. Historically they were treated as an order of turbellarian flatworms. About 400 species are known, but probably many more not yet described.
