flattened sea fan coral
Paramuricea placomus
Overview
The flattened sea fan coral (Paramuricea placomus) is a colonial soft coral species characterized by its distinctive fan-shaped, flattened branching structure that grows in a single plane. This Mediterranean endemic coral forms colorful colonies with polyps that extend to filter-feed on plankton and organic particles from the water column. As a habitat-forming species, it provides important three-dimensional structure on rocky substrates, creating shelter and feeding areas for numerous marine organisms including fish, crustaceans, and other invertebrates.
The flattened sea fan coral faces severe population declines primarily due to climate change impacts including ocean warming and acidification, which cause coral bleaching and reduced calcification rates. Additional pressures from fishing activities, coastal development, and pollution further compromise the survival of remaining populations in the Mediterranean Sea.
Habitat
Paramuricea placomus inhabits rocky substrates and vertical walls in the Mediterranean Sea, typically found at depths ranging from 15 to 200 meters in areas with moderate to strong water currents. The species thrives in well-lit zones where sufficient water flow provides the plankton and nutrients necessary for filter-feeding.
