Cauliflower Coral, scientifically known as Pocillopora damicornis, is a widespread and adaptable species of coral found in tropical and subtropical waters around the world. This coral is easily recognized by its characteristic branching growth pattern, resembling the florets of a cauliflower.
Description & Characteristics
The Cauliflower Coral, Pocillopora damicornis, exhibits a diverse range of shapes and sizes, with colonies typically reaching a maximum size of around 50 centimeters in diameter. Its branching structure is a defining feature, with numerous branches that spread out from a central base. These branches are often covered in small, rounded polyps that give the coral its distinctive cauliflower-like appearance. The color of Pocillopora damicornis can vary significantly, ranging from pale brown to deep orange, with some colonies displaying vibrant green or even purple hues. This coloration is influenced by the presence of symbiotic algae called zooxanthellae, which live within the coral’s tissues.
Habitat and Occurrence
Pocillopora damicornis is a highly adaptable species found in a variety of marine environments. It thrives in both shallow and deeper waters, ranging from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. This broad depth range allows the Cauliflower Coral to occupy various marine zones, including the subtidal, sublittoral, infralittoral, and deep zone of the oceans. Its neritic habitat preference suggests that it is commonly found in coastal waters, where it can benefit from nutrient-rich currents and ample sunlight.
Taxonomy
The Cauliflower Coral, Pocillopora damicornis, is a member of the Class: Hexacorallia, Order: Scleractinia, and Family: Pocilloporidae. This classification places it within the group of hard corals, which are characterized by their rigid skeletons made of calcium carbonate. The family Pocilloporidae comprises several species of branching corals, known for their rapid growth and distinctive skeletal structures.
Feeding
Pocillopora damicornis obtains nutrients through a combination of two methods. It feeds on plankton, tiny organisms that drift in the water column, by capturing them with its polyps. Additionally, the coral hosts symbiotic zooxanthellae, which provide the majority of its energy through photosynthesis. These microscopic algae reside within the coral’s tissues and utilize sunlight to produce sugars that are then shared with the host coral. The symbiotic relationship between the Pocillopora damicornis and its zooxanthellae highlights the importance of light in its survival and growth.
