The multicoloured sea fan, Acabaria rubra, is a species of gorgonian sea fan in the family Melithaeidae.[1]
Description
The sea fan colony grows up to about 30 cm high, with branches of between 2 and 4 mm. It is bushy with thin cylindrical branches which are often tangled or joined. The polyps emerge from knobs on the surface of the colony. It is variably coloured, with the colony being red, yellow, white or pink, and the individual polyps being white, yellow or red.[2]
Distribution
This sea fan is found only around the South African coast from Bloubergstrand to East London in 10–30 m of water. It is endemic to this region.
Ecology
These sea fans are found on vertical surfaces on reefs and under overhangs, usually orientated perpendicularly to the water flow. It may grow in assemblages with sponges, bryozoans or tunicates. It is preyed upon by the coral nudibranch, Phyllodesmium horridum, as well as the walking anemone, Preactis millardae.[3]
