Codosiga, a collar flagellate. This genus includes solitary and colonial forms. Here we see several colonies of cells forming tight aggregates at the end of a long stiff stalk. Each cell has a single apical flagellum surrounded by a collar of fine pseudopodia. The collar captures food swept against it by the action of the flagella. Phase contrast.
