Ontogeny of Calymne relicta from MCZ 8571, R/V ‘Atlantis’ cruise 24, station 122. For each set of drawings, from left to right: apical view, oral view, and left side. The periproct and peristome are in black, and the interambulacral plates are shaded. In some specimens, the sutures are omitted because they were not discernible, and only primary tubercles are shown (some still with spines attached). All scale bars are 1 mm long. A, just-postlarval imago. B, very small juvenile. C, larger juvenile with periproct separated from apical system. from Saucède, T., Mironov, A. N., Mooi, R. & David, B. 2009.
