SOME cOlONIES Of C. gracilis  HAvE A fEW POlyPS THAT lAck OL ScAlES ON ONE OR bOTH SIdES, bUT IN THIS cASE THE AbSENcE IS cOMPENSATEd by A bROAd bASAl lObE Of THE OL OPERcUlAR ScAlE, WHIcH AlSO OccUPIES AT lEAST PART Of THE SPAcE OTHERWISE cOvEREd by THE

INNER-lATERAl MARgINAl. THE NUMbER Of AbAXIAlS IS TyPIcAlly fOUR OR fIvE, IN SOME cOlONIES SIX TO SEvEN, ANd THE SclERITES MAybE SlIgHTly ScUlPTUREd EXTERNAlly WITH ANASTOMOSINg RIdgES.

gEOgRAPHIc dISTRIbUTION WITH C. gracilis  ANd C. americana  , ANd IS A cOMPONENT Of dIvERSE cOMMUNITIES fORMEd by SEvERAl cORAl SPEcIES. FOR EXAMPlE, IN ONE STATION (Ger-503), AT lEAST 15 OTHER OcTOcORAl SPEcIES WERE cOllEcTEd, MOSTly cAlcAXONIANS. AddITIONAlly, AS IN OTHER PRIMNOIdS, cOlONIES Of C. lucaya  MAy bE INfESTEd WITH OPHIUROIdS, WHIcH TIgHTly ENTWINE THEIR ARMS AROUNd THE gORgONIAN bRANcHES bUT SEEM TO dO NO HARM.
