  1. The first three principal components are shown, calculated from 14 skeletal traits measured on E. flexuosa, collected from the 12 locations (seven reefs were included). The character codes are: club length (CL), club width (CW), capstan length (CAL), capstan width (CAW), spindle length (SL), spindle width (SW), calice diameter (CD), intercalice distance (ID), surface area (SA), polyp density (PD), branch thickness (BT), terminal branch number (TBN) terminal branch average length (TBL) and colony height (CH).
