Stony coral tissue loss disease (SCTLD) is a disease that affects stony corals, which are a type of coral that form the structural foundation of coral reefs. SCTLD is characterized by the loss of living tissue from the surface of the coral, leaving a skeleton behind. The disease can affect a variety of coral species, including elkhorn coral, staghorn coral, and finger coral. SCTLD is a major threat to coral reefs, as it can significantly reduce the ability of reefs to provide habitat and support biodiversity. The cause of SCTLD is unknown, but it is thought to be caused by a combination of factors, including environmental stressors, such as water pollution and temperature changes, as well as pathogenic organisms. There is no known cure for SCTLD, and efforts to manage the disease focus on reducing stressors and promoting coral resilience.
