Fig. 1 in Ultrastructural Studies on a Model Tintinnid - Schmidingerella meunieri (Kofoid and Campbell, 1929) Agatha and Strüder-Kypke, 2012 (Ciliophora). I. Somatic Kinetids with Unique Ultrastructure

Fig. 1. Schmidingerella meunieri from the Northeast Pacific in vivo (A), in the scanning electron microscope (B), and in the transmission electron microscope (C) and a kinetal map of a congener after protargol staining (D). (A) The living cell is attached by its peduncle to the bottom of the lorica. (B) Contracted, naked specimen. (C) Longitudinal ultrathin section. (D) Scheme of ciliary pattern in Schmidingerella arcuata (modified from Agatha and Strüder-Kypke 2012). AM, adoral membranelles; DK, dorsal kinety; L, lorica; LA, lateral ciliary field; LF, left ciliary field; Pe, peduncle; RF, right ciliary field; SC, somatic cilia; VK, ventral kinety. Scale bars: 50 µm (A, C), 20 µm (B).
