Flabellum is a genus of corals in the family Flabellidae. These corals are known for their distinctive fan-shaped structures, which contribute to their common name, "fan corals." Flabellum species are found in various marine environments, often in deep-sea habitats.

Description

Flabellum corals are characterized by their solitary, non-colonial growth form. They possess a calcareous skeleton that is typically fan-shaped or cup-shaped. The corallites, or skeletal cups that house the polyps, are large and prominent. The polyps themselves have numerous tentacles that they use for feeding and defense.

Habitat

Flabellum species are primarily found in deep-sea environments, often at depths ranging from 200 to 2000 meters. They are typically located on soft substrates such as mud or sand, where they anchor themselves using their robust skeletons. These corals are adapted to cold, dark conditions and are often found in regions with strong currents.

Distribution

The distribution of Flabellum corals is global, with species recorded in the Atlantic, Pacific, and Indian Oceans. They are particularly abundant in the deep waters off the coasts of New Zealand, Japan, and the Antarctic region.

Species

The genus Flabellum includes several species, some of which are:

• Flabellum alabastrum
• Flabellum angulare
• Flabellum australe
• Flabellum curvatum
• Flabellum impensum

Ecology

Flabellum corals play a significant role in deep-sea ecosystems. They provide habitat and shelter for various marine organisms, including crustaceans, mollusks, and small fish. These corals are also involved in nutrient cycling within their environments.

Conservation

Like many deep-sea organisms, Flabellum corals are vulnerable to threats such as deep-sea fishing, mining, and climate change. Conservation efforts are essential to protect these unique corals and their habitats. Marine protected areas and regulations on deep-sea activities are some measures that can help in their conservation.

Research

Research on Flabellum corals is ongoing, with scientists studying their biology, ecology, and potential applications. These corals are of interest due to their unique adaptations to deep-sea environments and their potential use in biotechnology and medicine.
