Acropora indonesia is a coral species found in the Indo-Pacific region. It is a member of the Acroporidae family, a diverse group of corals known for their branching and table-like growth forms. This species is characterized by its distinctive features and ecological importance, contributing significantly to the biodiversity and functioning of coral reefs.
Description & Characteristics
Acropora indonesia exhibits a branching growth form, similar to many other Acropora species. Its colonies can reach a considerable size, contributing to the structural complexity of coral reefs. The coral polyps, which are the individual animals that make up the colony, are small and have a distinctive morphology. The species is distinguished by its corallite structure, which is unique among Acropora species.
Habitat and Occurrence
Acropora indonesia is found in a variety of marine environments, including subtidal, sublittoral, and infralittoral zones. These zones encompass the deep zone of the oceans, extending from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. This species is often found in areas with clear water, moderate wave action, and abundant sunlight. Acropora indonesia thrives in neritic environments, which are the waters over continental shelves. Its presence within these varied marine zones highlights its ecological adaptability.
Taxonomy
Acropora indonesia belongs to the Class: Hexacorallia, Order: Scleractinia, and Family: Acroporidae. The Hexacorallia class comprises corals, sea anemones, and other cnidarians characterized by having six or multiples of six tentacles. The Order Scleractinia includes stony corals, which are known for their hard skeletons made of calcium carbonate. The Family Acroporidae encompasses a wide range of branching and table-like corals, contributing significantly to the structure and diversity of coral reefs worldwide.
Feeding
Acropora indonesia is a heterotrophic organism, meaning it obtains its nutrition from other sources. It relies on a combination of feeding strategies to acquire essential nutrients. This includes capturing and consuming small organisms like plankton, as well as utilizing the process of suspension feeding. These corals also harbor symbiotic zooxanthellae, single-celled algae that live within their tissues. These algae perform photosynthesis, producing sugars and other nutrients that benefit the coral. This symbiotic relationship is crucial for the survival and growth of Acropora indonesia.
