Thin Finger Coral

Porites divaricata

Thin Finger Coral, scientifically known as Porites divaricata, is a reef-associated coral species found primarily in the Western Central Atlantic, particularly in the Caribbean region. It thrives in shallow, protected reef environments, often amidst seagrass beds. This coral forms colonies of thin, fused branches with distinct flattened tips. Its coloration ranges from uniform grey-brown to greenish-yellow, and its tentacles are usually extended during the day, which is a characteristic feature that can help divers identify it. Thin Finger Coral is typically found at depths ranging from the surface to 47 meters, although most occurrences are recorded at depths shallower than 40 meters, with a significant majority found above 30 meters. As a member of the class Anthozoa, its reproductive strategy includes both gonochoric and hermaphroditic individuals. Mature gametes are released into the coelenteron and then spawned through the mouth, with the zygote developing into a planktonic planula larva before settling. For divers encountering Thin Finger Coral, it presents a harmless and serene presence on the reef. Its status is listed as Least Concern on the IUCN Red List, and it is included in CITES Appendix II.
