Correction to: Coral Reefs https://doi.org/10.1007/s00338-019-01885-7

Following the online publication of Bridge et al. 2020 it was brought to our attention by Bert Hoeksema that the Critically Endangered species, Siderastrea glynni Budd & Guzman 1994, had recently been synonymised as S. siderea, Ellis & Solander 1786 (Glynn et al. 2016). Therefore, we have revised the second sentence of the second paragraph of the Results to read “The three species listed as critically endangered are split among two families: Acroporidae and Poritidae.” We have also revised Figure 2 to reflect that fact that the family Siderastreidae contains no species listed as Critically Endangered.

We also note that despite being synonymised in 2016, S. glynni is still listed as Endangered by NOAA under the Endangered Species Act (https://www.fisheries.noaa.gov/species/siderastrea-glynni-coral), is regarded as the coral with the highest EDGE score (http://www.edgeofexistence.org/species/siderastrea-glynni), and is still the subject of a petition to protect the now-synonymised species (https://www.change.org/p/world-wildlife-fund-protectthe-critically-endangered-siderastrea-glynni-coral-reef). These examples highlight the necessity for researchers and managers to stay abreast of the many recent changes to coral taxonomy by regular visits to sites such as the World Register of Marine Species (WoRMS, http://www.marinespecies.org/) (Hoeksema and Cairns 2020). In addition, the transplantation of S. siderea from the Atlantic to the eastern Pacific that resulted in the incorrect description of a new species (Glynn et al. 2016) highlights the potential pitfalls of moving organisms outside of their native geographical range.
