| Abstract | A detailed account of the structure and musculature of the mouth tube and mode of feeding in P. narcinae is presented. The double-walled mouth tube is formed by a close fitting of the lateral, longitudinal ridges of the labium into the longitudinal groove of the inner, lateral edges of the labrum. The musculature of the mouth tube consists of two pairs of retractores oris, four pairs of compressores labri and two pairs of levatores labii. The host tissues are scraped off by the mandibles repeating a very characteristic movement brought about by roto adductor mandibulae and roto abductor mandibulae pair of muscles. The tissue particles are forced into the buccal cavity with the help of labral muscles. The suction is broken by the contraction of levatores labii group of muscles. |
