Convoluta convoluta is a small acoel in the family Convolutidae. Native to the Baltic Sea, it invaded the Gulf of Maine in the late 1990s.[2]

Diet and symbiosis[]

This flatworm consumes juvenile settling mussels and harpacticoid copepods.[3] It also engages in a symbiosis with a diatom of the genus ,[4] which has also invaded the Gulf of Maine.

Impact and ecology in the Gulf of Maine[]

In the Gulf of Maine, the impact of this species appears minimal as the habitat is presumably saturated with food, and the species is ultimately self-limited by species competition.[5] It also appears limited to wave-protected habitats, where it prefers filamentous algae.[5] In 2001, it occurred in densities of up to 19 per square centimeter.[2]
