Abstract
The orientation of fan shaped sessile organisms perpendicular to the current is well known and has often been discussed, REES 1972, RIEDL 1966, THEODORE and DENIZOT 1965, VELIMIROV 1973. The possible trophic benefit of this orientation in fan shaped coelenterates was pointed out by RIEDL 1966 and RIEDL and FORSTNER 1968. WAINWRIGHT and DILLON 1969 described the increased mechanical stability of Gorgonia against twisting moments. The effect of current on bilaterally symmetric coelenterates until now has been studied only by MAGNUS 1966, working on the nocturnal sea pen Scytaliopsis and by SVOBODA 1970, 1973 in the marine hydroid Aglaophenia.
