Pavona explanulata

Pavona explanulata is a coral species belonging to the family Agariciidae, commonly found in the Indo-Pacific region. This coral is typically associated with reef environments, thriving at depths ranging from 0 to 40 meters. Divers are most likely to encounter it on vertical reef walls, where it is more common, although it can also be found on subtidal reefs between 5 to 28 meters deep. Pavona explanulata is part of the Scleractinia order, known for its hard, calcium carbonate skeletons that contribute to reef building. This coral species has a unique reproductive strategy. Members of the class Anthozoa, to which Pavona explanulata belongs, can be either gonochoric or hermaphroditic. The mature gametes are released into the coelenteron and then spawned through the mouth. The life cycle begins when the zygote develops into a planktonic planula larva, which eventually undergoes metamorphosis, forming tentacles, septa, and a pharynx before settling on the substrate. While diving, encountering Pavona explanulata can be a subtle experience, as it does not have a common name or distinctive features that make it stand out immediately. However, its ecological role in reef building and its presence on vertical walls make it an interesting subject for observation. The species is currently listed as Least Concern on the IUCN Red List.
