Genus BODO (Ehr.) Stein.

(Stein '59, Bütschli '83; Klebs '92; Senn 1900.)

The body is naked, usually amoeboid in its changes, and provided with
two flagella, one of which is usually trailed along under and behind
the animal. The anterior end is usually pointed, with the flagella
arising from a minute depression; the posterior end is rounded.
Specific characters very difficult to analyze. Fresh and salt water.

The body during movement is globular or ovoid, without any anterior
process. The trailing flagellum is invariably much longer than the
vibratory one. The contractile vacuole lies in the anterior half of
the body. Solid food particles are taken in near base of flagella.

Length of body 9 to 12µ; diameter 8 to 11µ. Common.
