I find Peranema trichophorum in all my sites. This flagellate, which belongs to the Euglenophyceae, can be observed especially well on the floating cover glass, on which it often settles. It glides along the cover glass with a straight locomotion flagellum. The locomotion flagellum is described to be 1–1.5 X of the the body length. However, in my population I found specimens that had a locomotion flagellum twice of the body length (s. fig. 2 a-d). When swimming, Peranema trichophorum is often sac-shaped and one corner of the posterior end often protruding (s. fig. 1 a-d). The pellicle is distinctly striated and parallel to these stripes small rods are arranged of unknown function. In May 2014 I found a specimen in which these rods were assembled on the outside of the pellicle, giving the impression that the specimen was covered with bristles (s. fig. 4 a-d). In the literature I could not find any hint that these bristlest has been described before. Peranema trichophorum feeds heterotrophically and phagocytizes other protozoans. On one occasion I could observe Peranema trichophorum attacking a flagellate and tried to ingested it (s. fig. 3 a-d). The rods of the ingestion apparatus serves to widen the mouth opening and to bend back the locomotion flagellum. The attacked flagellate was obviously too large and was finally not phagocytosed.
