Stony Coral, scientifically known as Pocillopora meandrina, is a captivating species of coral found in various marine environments. Its intricate branching structure and vibrant colors add to the beauty of the underwater world.
Description & Characteristics
Pocillopora meandrina is a colonial coral characterized by its intricate, branching structure. Its branches, which can grow to a substantial size, are covered in numerous small polyps. These polyps, responsible for the coral’s feeding and reproduction, possess a central mouth surrounded by tentacles. The coral’s color can vary depending on its location and the presence of symbiotic algae, with shades of brown, yellow, green, and even orange being commonly observed. This coral species can reach a maximum size of around 1 meter in diameter, showcasing its impressive growth potential.
Habitat and Occurrence
Pocillopora meandrina is a species that thrives in the subtidal, sublittoral, and infralittoral zones of the oceans. This means it can be found from the lower limit of the intertidal zone, where it is occasionally exposed to air, down to depths of about 200 meters, residing in the neritic zone. Pocillopora meandrina is a common sight in these marine ecosystems, adding to the biodiversity and ecological balance of these areas.
Taxonomy
The Stony Coral, Pocillopora meandrina, is scientifically classified as follows: it belongs to the phylum Cnidaria, a group of aquatic invertebrates known for their stinging cells. Within this phylum, it is further categorized within the class Hexacorallia, characterized by polyps with six or multiples of six tentacles. It then falls under the order Scleractinia, commonly referred to as stony corals, which are distinguished by their hard, calcium carbonate skeletons. Finally, Pocillopora meandrina belongs to the family Pocilloporidae, a family of branching corals known for their intricate structures and vibrant colors.
Feeding
Pocillopora meandrina has a unique feeding strategy that combines two distinct methods. Its polyps extend tentacles to capture plankton, small organisms that drift in the water column, providing a primary source of nutrition. Furthermore, Pocillopora meandrina forms a symbiotic relationship with zooxanthellae, single-celled algae that live within its tissues. These algae, through photosynthesis, produce sugars that are then utilized by the coral, making light an essential component of its nutritional intake.
