FIGURE 23. Stichopathes cf. maldivensis Forster Cooper, 1903. (a–c) In situ pictures showing the different morphologies that this species displays. A branched appearance is sometimes seen as a consequence of a breaking event, as shown by the white arrow. (d) White phenotype (INV.131372) with contracted polyps. (e) Brown-orange phenotype (INV.151020) with expanded polyps. The polyp row is twisting around the stem. (f) Section of a distal fragment measuring 4.5 mm in diameter (INV.131370). Polypar side is on the right. (g) Tall cylindrical polypar spines. (h) Conical abpolypar spines. (i) Close-up view of an abpolypar spine showing the tuberculation occurring on only one side. (j) Secondary spines.
