There has been a building recent concern surrounding the potential of a new invasive species makings its way around the region. Unomia stolonifera is an octocoral usually found in the Indian and Pacific Oceans. However, it has been confirmed to be present in Venezuela, Cuba and Hawaii with a suspected case recently reported in Puerto Rico. The new report signals the potential for the species to be spread more widely across the region.
The soft coral is identified by colonies of polyps all with a central opening surrounded by 8 tentacles. The polyps grow on a stalk with an unusually large number of polyps also growing from the side. This soft coral is also known for its ability to reproduce quickly and outcompete native corals, ultimately smothering and displacing them.
What can you do?
- Reporting
As a threat that has the potential to further stress our local coral reef ecosystems, we are asking you to assist in reporting of any suspected cases of the soft coral. If spotted, the corals should be left undisturbed, and reporting should be prioritised. Anyone encountering the species should submit a GPS coordinate/location of the specimen along with a photograph to the CZMU by emailing Shoneé Howell (showell@coastal.gov.bb).
In cases where contact is made with the octocoral, there is the potential for it to be spread by divers’ gear. Therefore, it is asked that decontamination procedures are undertaken to prevent its spread. This includes soaking gear in freshwater for 5 mins.

Please feel free to share these resources with customers and friends alike in efforts to spread awareness.
The CZMU will continue to periodically offer updates as new information comes to light.
