Sea fan / Gorgonian fan coral

Gorgonia ventalina

MEDIUM
Family
Gorgoniidae
Also known as
Common sea fan, Venus sea fan, Purple sea fan
Description
A large, fan-shaped colonial coral that grows in a single plane perpendicular to the current to maximize filter feeding efficiency. It is characterized by a highly branched, lattice-like network of branches in shades of brown, purple, or tan. Found throughout the Caribbean and Atlantic, it hosts symbiotic zooxanthellae and filter-feeds on plankton.
Habitat
Coral reefs and rocky substrates in the Caribbean and tropical Atlantic; typically found at depths of 1–30 m, often oriented perpendicular to prevailing currents.
Conservation status
Least Concern
Notes
The fan coral dominates the center of the frame and is the most prominent element. Species-level ID is approximate — could be Gorgonia ventalina or a related gorgonian genus (e.g., Pseudopterogorgia or Muricella) given the brown coloration; without polyp detail a firm species ID is uncertain. The reef scene is richly diverse with multiple sponge and coral species visible. Image quality is good with clear blue water background.
