Porous Star Coral – Astreopora myriophthalma

The Porous Star Coral, scientifically known as Astreopora myriophthalma, is a fascinating species of stony coral that thrives in the vibrant underwater landscapes of the world’s oceans. This coral species is distinguished by its unique morphology and ecological significance, contributing to the biodiversity and health of coral reef ecosystems.

Description & Characteristics

The Astreopora myriophthalma is characterized by its distinctive porous, star-shaped corallites, giving rise to its common name. These corallites are typically small and closely spaced, creating a textured surface that resembles a star-studded sky. The coral colony can grow to a considerable size, often reaching several feet in diameter. This coral displays a vibrant color palette, ranging from shades of brown, green, and yellow to a captivating orange. The vibrant hues are influenced by the presence of symbiotic zooxanthellae algae that reside within the coral’s tissues.

Habitat and Occurrence

The Porous Star Coral, Astreopora myriophthalma, is a common inhabitant of the Subtidal, sublittoral, infralittoral, and deep zones of the oceans, primarily found within the neritic zone. This zone extends from the lower limit of the intertidal zone to the shelf edge, which typically lies at a depth of around 200 meters. This coral species is prevalent in these marine ecosystems, contributing to the structure and diversity of coral reefs.

Taxonomy

The species Astreopora myriophthalma belongs to the Class: Hexacorallia, Order: Scleractinia, and Family: Acroporidae. These classifications highlight the evolutionary relationships between the Porous Star Coral and other related coral species. This taxonomic framework provides a systematic understanding of its place within the broader coral reef community.

Feeding

Like many other coral species, Astreopora myriophthalma relies on a combination of feeding strategies to obtain essential nutrients. The coral captures microscopic plankton from the surrounding water column, which is a vital source of organic matter. Additionally, the symbiotic zooxanthellae residing within the coral’s tissues perform photosynthesis, providing the coral with a significant portion of its energy requirements. This symbiotic relationship is crucial for the survival and growth of Astreopora myriophthalma. The availability of light and nutrients within its environment is vital for the well-being of this coral species, making it a sensitive indicator of environmental conditions.
