Isophyllia
Isophyllia is a genus of stony corals in the family Mussidae. These corals are commonly known as “pillar corals” due to their distinctive pillar-like shape. They are found in the Indo-Pacific region and are characterized by their massive, columnar or branching growth forms. Their surfaces are often covered in numerous polyps that extend during feeding, creating a unique and striking appearance.
Common Names
Isophyllia corals are commonly referred to as "pillar corals" or "pillar polyps." Other less common names include "pillar coral" and "branching pillar coral."
Characteristics
Isophyllia corals exhibit several distinctive characteristics:
- Growth form: They primarily grow in massive, columnar, or branching forms.
- Corallites: Their corallites (individual coral polyps) are typically small and numerous, covering the entire surface of the coral colony.
- Color: Isophyllia corals can display a wide range of colors, including brown, green, yellow, and orange.
- Symbiosis: Like many other stony corals, they host symbiotic zooxanthellae algae within their tissues, which provide them with energy through photosynthesis.
Environment
Isophyllia corals are found in the Indo-Pacific region, inhabiting a variety of reef environments. They prefer clear, warm waters with moderate wave action. They typically occur in shallow depths, ranging from the intertidal zone to depths of around 30 meters.
