CCA triplots of the relationships between hermit crab species and their shells at Sepangar shore. Direction of arrow indicates the proportional increase in shell species used by hermit crabs. Solid circles indicate sampling stations/zones along transect. Filled and hollow triangles indicate hermit crabs D. tumidus (Dt) and D. klaasi (Dk), respectively. Filled and hollow squares indicate hermit crabs C. striolatus (Cs) and C. merguiensis (Cm), respectively. Cross indicates hermit crab D. pallescens (Dp). ‘M’, ‘F’ and ‘oF’ indicate male, non-ovigerous female and ovigerous female, respectively. Ellipsoid envelops the dominant hermit crab species at the indicated sampling stations.
