Photomicrographs of Tintinnopsis hemispiralis in vivo (ae) and after protargol staining (fj). a Lateral view of a representative individual. b Arrowheads show the spiral striations on lorica. c Fully extended individual with broken lorica; arrowhead shows the ciliary tuft. d Lorica of another individual. e Cell proper that abandoned the lorica; arrowhead shows elongated anterior cilia. f Ventral kinety and right ciliary fields; arrow shows the ciliary tuft; arrowheads indicate the nodules of the thick argyrophilic fibers. g Dorsal side, showing the left ciliary field, dorsal kinety, and posterior kinety; arrow marks the ciliary tuft. h Lateral side of an early divider; arrowheads mark macronuclear nodules; arrow shows the ciliary tuft. i Posterior kinety and dorsal kinety. j Arrowhead marks collar membranelles. DK, dorsal kinety; LA, lateral ciliary field; LF, left ciliary field; OP, oral primordium; PK, posterior kinety; RF, right ciliary field; P, peduncle; VK, ventral kinety. Scale bars = 75 μm (a, c), 60 μm (b, d), 25 μm (e), 15 μm (f), 20 μm (h)
