Acropora
Acropora is a genus of stony corals found in tropical and subtropical waters worldwide. These corals are known for their branching, tabular, and columnar growth forms, and their intricate skeletal structures contribute significantly to the formation of coral reefs. They are vital to the health of marine ecosystems, providing habitat and food for countless species.
Common Names
Acropora species are commonly known as "staghorn corals" due to their resemblance to the antlers of a stag. Other common names include "branching corals" and "table corals."
Characteristics
Acropora corals are characterized by:
- Branching, tabular, or columnar growth forms: These corals exhibit a wide range of growth patterns, from delicate, branching structures to massive, tabular formations.
- Small, densely packed polyps: The individual polyps of Acropora are relatively small and tightly clustered together.
- Calcium carbonate skeleton: Like all stony corals, Acropora species build their skeletons from calcium carbonate, which gives them their characteristic hard, rigid structure.
- Rapid growth rates: Many Acropora species are known for their rapid growth rates, which contributes to their dominance in reef ecosystems.
Environments
Acropora corals are found in a variety of marine environments, including:
- Coral reefs: Acropora species are key components of coral reefs, often forming the framework for these complex ecosystems.
- Lagoons: These corals can tolerate some degree of freshwater input and are often found in lagoons.
- Shallow reef flats: Acropora thrives in shallow, clear water with high light levels.
