Fig. 9 in Three-dimensional micro- and nanostructural characteristics of the scleractinian coral skeleton: A biocalcification proxy

Fig. 9. Galaxea fascicularis (Linnaeus, 1767); ZPAL H.23/7 (originally NMNH 90860 lot). Recent, North Pacific Ocean, Central Philippines (southern parts of islands), collection J.B. Steere. A, B. Morphology of distal septal edge (A) and septal flank spine (B). Note "Persian lamb" texture of skeletal surface (as shown by these fasciculi). C, D. Transverse section of polished and etched septum. Arrow in enlarged (D) fragment (general view in C) shows "blurry", probably organic material in dCRA and adjacent, radiating TD fibers (ca. 3–5 µm growth increments). E, F. Septum longitudinally sectioned in RAF plane; note dissolved/etched dRAF components in longitudinal "strand" (F enlargement). All are SEM.
