Why it matters: Corals are havens for biodiversity, providing shelter for over 25% of ocean animals, and they are major drivers of fishing and tourism revenue. Increasingly, climate change is threatening their viability.
The details: The preliminary results show that less than 22% of the approximately 1,500 staghorn coral surveyed are still alive.
Of the five reefs surveyed by NOAA's Mission: Iconic Reefs program and the Mote Marine Laboratory and Aquarium, only the two most northern ones, Carysfort Reef and Horseshoe Reef, had any living staghorn coral.
And of those surveyed, live elkhorn coral was only found at three sites.
No living staghorn or elkhorn corals were found at sample areas surveyed at Looe Key Reef, located in the lower Florida Keys, NOAA stated in a release.
