Acropora spathulata

Acropora spathulata is a species of coral belonging to the family Acroporidae. It is primarily found in the Indo-West Pacific region, thriving in tropical waters. This coral species is typically associated with intertidal reefs, particularly favoring areas with clear water. Divers are likely to encounter it on backreefs and reef flats, where it resides at depths ranging from 1 to 10 meters. The coral's structure and appearance can be distinguished by its branching formations, which are characteristic of many Acropora species. The reproductive cycle of Acropora spathulata involves the release of mature gametes into the coelenteron, which are then spawned through the mouth. The subsequent development of the zygote into a planktonic planula larva is a critical stage before it undergoes metamorphosis. During this process, the early morphogenesis of tentacles, septa, and pharynx occurs, eventually leading to larval settlement. This species is currently listed as Endangered on the IUCN Red List. Although harmless to humans, Acropora spathulata plays a vital role in the reef ecosystem, contributing to the biodiversity and structural complexity of coral reefs.
