Descriptions
Marine ciliate. Helicoprorodon gigans is a large contractile vermiform ciliate, reaching 2.5 mm in length when extended and 0.8-1 mm when contracted. Its pharyngeal apparatus is a tubular, posteriorly tapering apical basket, about 50-60 um long and about 8-10 um wide. According to light microscopy, one of the somatic kineties makes approximately 2 turns around the cytostome along a tight spiral, maked with a cytoplasmic ridge, the remaining kineties failing to reach the cytostome (Faure-Fremiet 1950; Fjeld 1955; Dragesco 1960; Raikov 1960). The exact number and arrangement of the kineties in the circumoral area remained however unknown. Fine structure of the circumoral ciliature and pharyngeal apparatus. (ref. ID; 7559)
