FIGURE 14. Cirrhipathes anguina (Dana, 1846) (a–h) In situ pictures showing the wide range of phenotypes that the species can present (a—INV.131378; b—INV.131369; c—INV.131373; d—INV.131379; e—INV.131360; f—INV.131359; g—INV.131362; h—INV.131363). All these phenotypes have the same spine morphology. (i) Distal section 0.48 mm in diameter from the 30 cm-long juvenile colony INV.131363. At this stage, regular rows of spines can be seen. (j) Distal section 3.5 mm in diameter of a 2.5 m tall colony INV.131379. The regular rows formed by the spines start to be lost. (k–n) Different spine morphologies seen on distal parts of Ci. anguina colonies. The spines are generally stout and papillose but irregular growths are sometimes found, as well as triangular, minute spines or cylindrical, narrow newly formed spines. (o) Triangular, laterally compressed spines from a distal fragment of the juvenile colony INV.131363.
