The sinuous sea fan (Eunicella tricoronata) is a species of gorgonian sea fan in the family Gorgoniidae.
Description This fan is flattened and has curving branches which all tend to grow in the same plane. It may be mustard yellow to orange and when feeding the extended polyps give the fan a fuzzy appearance. It may grow up to 1m tall and have branches of 0.7 to 1 cm wide.Branch, G.M., Branch, M.L, Griffiths, C.L. and Beckley, L.E. 2010. Two Oceans: a guide to the marine life of southern Africa
Distribution This sea fan is found only around the South African coast from the Cape Peninsula to East London in 9–36 m of water. It is endemic to this region.Jones, Georgina. A field guide to the marine animals of the Cape Peninsula. SURG, Cape Town, 2008.
Ecology This fan usually grows in deeper water, sheltered from wave action. It is preyed upon by the whip fan nudibranch, Tritonia nilsodhneri, which strongly resembles the feeding fan.
