Researchers at UC Santa Barbara have found that young corals are quite vulnerable to these predators, regardless of whether a colony finds itself alone on the reef or surrounded by others of its kind. The research, led by doctoral student Kai Kopecky, appears in the journal Coral Reefs. Kopecky and his co-authors were curious how corals can reemerge following large disturbances like cyclones and marine heatwaves, which periodically devastate the reefs of Mo’orea, French Polynesia, where the research was conducted.
