Janua heterostropha is a tubeworm polychaete belonging to the Spirorbinae. It has a broad global range being found in North America, Central America, South America, Europe, Africa, Asia, and Australia. Its native range is difficult to determine; however some authors believe it is native to Northern Europe where it shows its greatest range of climate, depth and habitat. It is considered introduced in South Africa, Hawaii, and New England (Rhode Island and Massachusetts), but is likely introduced to many other locations. It is found attached to seaweeds, rocks, shells, pilings, and other solid structures. No ecological or economic impacts are currently known for this species.
