The Oval Mushroom Coral, scientifically known as Lithophyllon repanda, is a striking and unique coral species distinguished by its distinctive oval shape and intricate skeletal structure. It thrives in a variety of marine environments, contributing significantly to the biodiversity of these underwater ecosystems. This description explores the intriguing characteristics, habitat, and ecological role of this fascinating coral species.

Description & Characteristics

The Oval Mushroom Coral, Lithophyllon repanda, earns its name from its characteristic oval shape. This coral species exhibits a robust skeletal structure, forming a flattened, disc-like colony with a prominent, central point. The colony surface is covered in numerous, short, radial corallites, which give the coral a textured and somewhat bumpy appearance. The color of the Lithophyllon repanda can vary, ranging from pale brown to vibrant shades of yellow and orange, adding to its visual appeal.

Habitat and Occurrence

The Oval Mushroom Coral thrives in a variety of marine zones, including the subtidal, sublittoral, infralittoral, and deep zones of the oceans. It is commonly found from the lower limit of the intertidal zone, extending to the shelf edge at approximately 200 meters water depth. This adaptable species, classified as neritic, thrives in diverse marine environments, ranging from shallow coastal areas to deeper, continental shelf regions. Its presence is a testament to its ability to thrive in a range of conditions, contributing to the rich biodiversity of these ecosystems.

Taxonomy

The Lithophyllon repanda belongs to the Class: Hexacorallia, Order: Scleractinia, and Family: Fungiidae. These taxonomic classifications reflect its close evolutionary relationships with other coral species and place it within a broad and diverse group of marine invertebrates.

Feeding

The Oval Mushroom Coral, Lithophyllon repanda, like many other coral species, utilizes a combination of feeding strategies to obtain sustenance. It relies on both plankton and zooxanthellae for its nutritional needs. Plankton, microscopic organisms that drift in the water column, are captured and consumed by the coral’s polyps. Zooxanthellae, symbiotic algae that reside within the coral’s tissues, contribute to the coral’s food supply through photosynthesis, providing energy from sunlight. This dual feeding strategy makes Lithophyllon repanda a highly adaptable species, capable of thriving in various marine environments.
