flagella

Description:

Coronympha (corr-o-nymph-a), a calonymphid flagellate which is a multinucleated trichomonad flagellate. All members of this group have multiple nuclei each with its own set of flagella. This genus has 8 or 16 karyomastigonts arranged in a single anterior circle. Each karyomastigont comprises three anterior flagella, a thick recurrent flagellum with an adherent proximal portion underlain by a cresta, an axostyle-pelta complex, and a drop-shaped parabasal close to the nucleus. The axostylar trunks are independent and only meet posteriorly, sometimes forming a caudal projection (see thumbnail). Four sets of flagella can be seen in this image, and a set seems to include 4 flagella (lower right). Phase contrast.
