Cyphastrea decadia

Cyphastrea decadia is a coral species found in the tropical waters of the Western Pacific. It is part of the family Merulinidae and is associated with reef environments. This coral is typically found at depths shallower than 40 meters, with most occurrences recorded at depths less than 20 meters. Divers may encounter this species at various dive sites where it contributes to the complex structure of coral reefs. The life cycle of Cyphastrea decadia involves a planktonic planula larva stage, which eventually settles and undergoes metamorphosis. This process includes the development of tentacles, septa, and a pharynx before the coral becomes sessile. Reproduction can occur through both gonochoric and hermaphroditic means, with mature gametes being released into the coelenteron and spawned through the mouth. Cyphastrea decadia is currently listed as Least Concern on the IUCN Red List. Divers observing this coral may notice its role in the reef ecosystem, providing habitat and contributing to the biodiversity of the area.
