The Thin Leaf Lettuce Coral, scientifically known as Agaricia tenuifolia, is a captivating coral species renowned for its unique morphology and ecological significance. This coral is widely recognized for its thin, leaf-like plates that extend outwards, resembling a delicate lettuce, giving it its common name.
Description & Characteristics
The Thin Leaf Lettuce Coral, Agaricia tenuifolia, is easily recognizable by its distinctive thin, leaf-like plates that can grow up to several inches in length. The plates are typically arranged in a fan-like pattern, creating a visually stunning display on the reef. These plates are often adorned with intricate patterns and grooves, further enhancing their aesthetic appeal. The coral’s color can vary greatly, ranging from shades of brown and green to vibrant orange and yellow, depending on environmental factors and the presence of symbiotic algae.
Habitat and Occurrence
Agaricia tenuifolia is a common sight in the Intertidal (Eulittoral) zone, the intertidal zone between the high and low tide lines characterized by the alternation of low and high tides. It thrives in this dynamic environment, where it is exposed to both air and water. This coral species is typically found attached to rocks, and other hard substrates. While it has a wider distribution, Agaricia tenuifolia prefers sheltered areas, and is often found in shallow reef environments, where it is exposed to abundant sunlight.
Taxonomy
The species Agaricia tenuifolia belongs to the Class: Hexacorallia, an order known for their six-sided symmetry, and the Order: Scleractinia, which includes stony corals, distinguished by their hard skeletons made of calcium carbonate. This coral is further categorized into the Family: Agariciidae, a family characterized by its thin, plate-like colonies.
Feeding
Like other corals, Agaricia tenuifolia employs a combination of feeding strategies to obtain sustenance. It relies on symbiotic algae called zooxanthellae living within its tissues, which produce energy through photosynthesis using sunlight. This provides the coral with a significant portion of its nutritional needs. Additionally, Agaricia tenuifolia captures food particles from the water column, such as plankton and dustfood, using its tentacles.
