FIGURES 9–14 in Last snails standing since the Early Pleistocene, a tale of Calliostomatidae (Gastropoda) living in deep-water coral habitats in the north-eastern Atlantic

FIGURES 9–14. Calliostoma bullatum on various substrates. 9. MSM16-3/GeoB 14871 (ROV4). Grazing on hydroids. 10. MSM16-3/GeoB 14871 (ROV4). Elongated, muscular foot supports feeding on polyp tissue (Madrepora oculata). Operculum and dorsal groove on foot indicated by arrow. 11. MSM16-3/GeoB 14873 (ROV7). Muscular foot enables elevation of body above substrate (live Lophelia pertusa). Epipodial sense organs spread directly below the shell (arrow). 12. MSM16-3/GeoB 14871 (ROV4). Feeding on apical portions of a live Madrepora oculata. 13. MSM16-3/GeoB 14779 (ROV2). Two individuals feeding on Lophelia pertusa tissue; note the grazing tracks showing the bare, white coral skeleton devoid of polyp tissue in contrast to the orange to pale-pinkish live portions. 14. MSM16-3/GeoB 14891 (ROV9). Three individuals of different sizes all feeding on epibionts of Lophelia pertusa framework; note the grazing traces on adjacent live Lophelia pertusa portions (see arrow).
