Staghorn Coral
Acropora cervicornis
IUCN · Critically Endangered
Acropora cervicornis is a fast-growing branching coral characterized by cylindrical, antler-like branches with pale white growing tips, as clearly visible in this image. It was once the dominant reef-building coral across the Caribbean but has suffered population declines of over 80% due to disease, bleaching, hurricanes, and water quality degradation. It is listed as Critically Endangered on the IUCN Red List and is protected under the U.S. Endangered Species Act. Active restoration efforts, including coral gardening and outplanting programs, are underway throughout its range.
