Crown-of-thorns starfish (COTS) are infamous in the marine world. Their toxin-loaded thorns give them a menacing appearance, and they have a reputation as destroyers of coral reefs. New research from the University of Sydney challenges the perception of COTS as purely destructive. The findings suggest controlled populations can have a positive impact on coral prevalence and diversity.
