Gorgonia

Gorgonia is a genus of octocorallian soft corals in the family Gorgoniidae. These corals are commonly called “sea fans” due to their distinctive fan-shaped morphology. They are widespread throughout tropical and subtropical waters, playing a crucial role in marine ecosystems.

Characteristics

Gorgonians are colonial organisms, composed of numerous tiny polyps that are connected by a central axis called a "sclerite." The sclerite provides structural support and is often made of calcium carbonate or gorgonin, a tough protein. Their branches are typically flat and fan-shaped, often adorned with intricate patterns of polyps and spicules (small, needle-like structures). The polyps are responsible for feeding and reproduction. They extend tiny tentacles to capture zooplankton and other small organisms.

Environments

Gorgonia species are found in a variety of marine environments, including coral reefs, rocky outcrops, and seagrass beds. They prefer clear, well-lit waters with moderate water currents. Sea fans typically attach themselves to solid substrates, such as rocks, coral skeletons, or even shipwrecks.

Common Names

Common names for Gorgonia species include:

  • Sea fans
  • Fan corals
