The False Pillow Coral – Pseudosiderastrea tayamai is a captivating stony coral species that graces the underwater landscapes of the Western Atlantic Ocean. This coral, characterized by its distinctive pillow-like shape and intricate patterns, is an integral part of the vibrant coral reef ecosystems it calls home.
Description & Characteristics
The Pseudosiderastrea tayamai is aptly named for its resemblance to a pillow. Its massive, rounded colonies can reach impressive sizes, often exceeding 1 meter in diameter. The surface of these colonies is adorned with numerous small, star-shaped polyps, each housing a single, small mouth surrounded by tentacles. These polyps, responsible for feeding and reproduction, contribute to the coral’s intricate, textured appearance. The color palette of this coral species is equally striking, ranging from shades of brown and gray to more vibrant hues of orange and yellow.
Habitat and Occurrence
The Pseudosiderastrea tayamai is a common sight in the shallow, tropical waters of the Western Atlantic Ocean. This coral thrives in the neritic zone, specifically in the epipelagic zone, which is characterized by abundant sunlight penetration. Its preferred habitat includes rocky reefs, sand bottoms, and even mangrove environments, where it establishes itself as a significant component of the local ecosystem.
Taxonomy
The Pseudosiderastrea tayamai is classified within the animal kingdom, belonging to the phylum Cnidaria. Within this phylum, it is further categorized into the Class: Hexacorallia, Order: Scleractinia, and Family: Rhizangiidae. This taxonomic classification reflects its close relationships with other stony coral species and emphasizes its unique evolutionary history.
Feeding
The Pseudosiderastrea tayamai employs a dual feeding strategy, leveraging both autotrophic and heterotrophic mechanisms. During the day, the coral’s symbiotic relationship with zooxanthellae, microscopic algae residing within its tissues, provides a significant portion of its energy needs. These algae photosynthesize, producing organic compounds that the coral can utilize. However, the Pseudosiderastrea tayamai also actively captures plankton at night, extending its tentacles to filter small organisms from the water column. This combination of feeding strategies makes this coral species highly adaptable and successful in its environment.
