Solitary journey (enlarged)

The body of this flagellate is long and thin, and its single flagellum extends forward and remains stiff, except for actively vibrating the very tip. Occasionally the flagellate contracts its body to change directions, but usually it travels in a straight line.

Commentary by Prof. Yuji Tsukii, Hosei University
This flagellate belongs to genus Peranema, most likely Peranema trichophorum, but there is scarce research available about this genus.

In the field, we can see flagellates in the Peranema genus that are clearly different from P. trichophorum, but unfortunately names have not been assigned to all the individual species.
