Islamorada (United States) (AFP) – Biologists in Florida are fighting to save the species that make up the only coral reef in the United States’ continental waters. They’ve recreated the coral reef habitat found in the waters off the southern tip of the state in huge aquariums in a bid to preserve it from a disease that is affecting the coral in the wild. Stony coral tissue loss disease, or SCTLD, has killed about half of stony coral species.
