Psammocora
Psammocora is a genus of colonial stony corals in the family Pocilloporidae. They are commonly known as “branching corals” due to their distinctive growth form. These corals are widely distributed throughout the Indo-Pacific region, with some species also found in the Red Sea and the western Atlantic Ocean.
Characteristics
Psammocora corals are characterized by their branching and encrusting growth forms. They typically exhibit a porous, "honeycomb" structure with numerous small, round polyps. These polyps are responsible for feeding and reproduction, and their arrangement gives the coral its distinctive appearance. The coral skeleton is composed of calcium carbonate, which is secreted by the polyps. These corals are typically brightly colored, ranging from shades of brown and green to yellow and orange. Their color can vary depending on the specific species, environmental conditions, and the presence of symbiotic algae.
Environment
Psammocora corals prefer shallow, reef environments with good water circulation and ample sunlight. They are typically found in areas with high water clarity and low sediment load. These corals are often exposed to strong wave action, which helps to keep them clean and prevents the build-up of sediment on their surface. They play a vital role in coral reef ecosystems, providing habitat for a variety of fish and invertebrates.
Species
The genus Psammocora includes several species, including:
- Psammocora profundaclava
- Psammocora contigua
- Psammocora stellata
- Psammocora digitata
- Psammocora nierstraszi
