Acropora awi is a species of branching coral belonging to the genus Acropora. Known for its intricate branching structure and vibrant colors, Acropora awi plays a vital role in coral reef ecosystems. This species is a common inhabitant of the Indo-Pacific region, contributing to the biodiversity and ecological balance of these underwater environments.
Description & Characteristics
Acropora awi is characterized by its branching growth form, often creating a complex network of interconnected branches. The coral colonies can grow to a considerable size, reaching a maximum height of several meters. The surface of the coral is covered in numerous polyps, which are tiny, individual organisms responsible for the coral’s feeding and growth. The polyps of Acropora awi typically exhibit a range of colors, including shades of brown, green, yellow, and orange, adding to the vibrant tapestry of the reef ecosystem.
Habitat and Occurrence
Acropora awi is a species that thrives in the subtidal zone, extending from the lower limit of the intertidal zone to the shelf edge at about 200 m water depth. This coral species is commonly found in the neritic zone, encompassing the coastal waters of the Indo-Pacific region. This geographic distribution allows it to inhabit a variety of marine environments, from shallow reefs to deeper, more sheltered areas.
Taxonomy
The species Acropora awi belongs to the Class: Hexacorallia, Order: Scleractinia, and Family: Acroporidae. This classification reflects the evolutionary relationships of Acropora awi within the broader framework of coral diversity. The genus Acropora encompasses a significant number of species, all of which share distinctive characteristics that distinguish them from other coral groups.
Feeding
Acropora awi is a suspension feeder, relying on a combination of sources for its nourishment. The coral polyps capture food particles suspended in the water column, including dissolved inorganic substances such as NaCL, CA, Mag, K, and I.P, as well as dissolved organic substances. Additionally, Acropora awi benefits from dust food and plankton that drift past the coral colonies. Perhaps the most important source of nutrition for Acropora awi is its symbiotic relationship with zooxanthellae. These microscopic algae live within the coral’s tissues and produce energy through photosynthesis, providing a significant portion of the coral’s food requirements. Light is essential for the zooxanthellae to thrive, and this symbiotic relationship makes Acropora awi dependent on clear water conditions for optimal growth and survival.
