The Large Polyp Stone Coral, scientifically known as Echinophyllia aspera, is a captivating and intriguing coral species distinguished by its unique morphology and ecological significance. Its large, prominent polyps, characteristic of its common name, are a hallmark of this fascinating marine organism. This species plays a crucial role in maintaining the health and diversity of coral reef ecosystems.
Description & Characteristics
Echinophyllia aspera exhibits a striking appearance, showcasing large, fleshy polyps with a distinctive, uneven surface. Each polyp can reach a considerable size, contributing to the coral’s overall robust form. Their coloration varies, ranging from vibrant hues of green and brown to more subdued shades of gray. The polyps, studded with numerous tentacles, are often arranged in a somewhat irregular pattern, contributing to the coral’s visually captivating presence.
Habitat and Occurrence
The Large Polyp Stone Coral thrives in a variety of marine environments, demonstrating its adaptability. It is commonly found in the subtidal, sublittoral, and infralittoral zones, inhabiting the region extending from the lower limit of the intertidal zone to the shelf edge at approximately 200 meters in depth. Echinophyllia aspera is characteristically present in neritic zones, showcasing its preference for these specific marine ecosystems.
Taxonomy
The species Echinophyllia aspera belongs to the Class: Hexacorallia, Order: Scleractinia, and Family: Lobophylliidae. This taxonomic classification places it within a larger group of corals, highlighting its evolutionary relationships with other species.
Feeding
Echinophyllia aspera, like many coral species, employs a dual strategy for obtaining sustenance. They possess zooxanthellae, symbiotic algae residing within their tissues, which provide a significant portion of their nutritional requirements through photosynthesis. Additionally, Echinophyllia aspera feeds on plankton, capturing these microscopic organisms from the surrounding water column. This combination of photosynthetic and heterotrophic feeding allows the coral to thrive in its diverse habitat.
