Eunicella singularis, the white gorgonian, is a species of colonial soft coral, a sea fan in the family Gorgoniidae.

[2] The polyps of Eunicella singularis feed by spreading their tentacles to intercept zooplankton and organic particles floating past.

[4] A laboratory study found that at 24 °C (75 °F), thermal stress caused the polyps to remain unexpanded (and thus not feeding), respiration was decreased, and photosynthesis stopped (although the symbionts were still present).

The sea fan was able to live on its reserves for several weeks during thermal stress before necrosis set in, but it recovered fully when the water temperature fell sufficiently.

[5] The bare areas where the mollusc has removed the coenenchyme tissue soon become colonised by epibionts such as algae, tube worms, bryozoans, and colonial tunicates.
