The Purple Lettuce Coral, scientifically known as Agaricia agaricites, is a striking and unique coral species that adds vibrant hues to the diverse marine ecosystems it calls home. This coral boasts a distinctive appearance, with its branching structure and vibrant purple coloration making it a standout amongst the myriad of underwater life.
Description & Characteristics
The Purple Lettuce Coral, Agaricia agaricites, is easily recognized by its distinctive growth form. It typically develops into plate-like or leaf-like structures, often resembling the lettuce for which it is named. The coral’s surface is covered in small, individual polyps, which are the feeding units of the colony. These polyps are responsible for the vibrant purple hue that gives this coral its common name. The Purple Lettuce Coral, Agaricia agaricites, can grow to a considerable size, reaching a maximum diameter of around 1 meter.
Habitat and Occurrence
The Purple Lettuce Coral, Agaricia agaricites, thrives in a variety of marine environments, showcasing its adaptability and resilience. It is commonly found in the subtidal, sublittoral, and infralittoral zones, inhabiting the deep zones of the oceans from the lower limit of the intertidal zone to the shelf edge at about 200 meters water depth. This coral species is typically found in the neritic zone, which is the area of the ocean that lies above the continental shelf.
Taxonomy
The Purple Lettuce Coral, Agaricia agaricites, is classified within the animal kingdom, belonging to the phylum Cnidaria. It is further categorized within the Class Hexacorallia, which includes corals, sea anemones, and other related organisms. The Purple Lettuce Coral, Agaricia agaricites, is part of the Order Scleractinia, encompassing stony corals that secrete hard, calcium carbonate skeletons. Lastly, it belongs to the Family Agariciidae, a family of stony corals characterized by their distinctive, plate-like or lettuce-like growth forms.
Feeding
Like most other corals, the Purple Lettuce Coral, Agaricia agaricites, relies on a combination of feeding strategies to obtain sustenance. It harbors symbiotic zooxanthellae within its tissues, microscopic algae that provide the coral with a significant portion of its energy through photosynthesis. Additionally, the Purple Lettuce Coral, Agaricia agaricites, captures small plankton organisms, such as zooplankton, from the water column, supplementing its diet with these nutrient-rich prey items.
