flagellate & pseudopodia
Hyperamoeba (hype-err-a-me-ba) a genus of flagellates with only a couple of species, very similar to the unicellular forms of the myxomycete slime moulds - with which it probably has affinities. Flagellated cells with one or two flagella, if two, one long one short. One long flagellum evident in this image. The cell body is clearly amoeboid. May also have an anterior projection. Phase contrast. This picture was taken by David Patterson, Linda Amaral Zettler, Mike Peglar and Tom Nerad from cultures and other materials maintained at the American Type Culture Collection during 2001.

Hyperamoeba
From the collection
American Type Culture Collection
| Description of Hyperamoeba: Circumscription: Heterotrophic protist with amoeboid and gliding (uni)flagellated stages, flagellated stage uniflagellated, and reminiscent of pelobionts but with tubulocristate mitochondria. Cysts also produced. Ultrastructural identity: Mitochondria with tubular cristae, some with central core, dictyosome present cristate. Two apical basal bodies give rise to four microtubular rootlets, two conical arrays of microtubules extend toward nucleus and centre of cell. Synapomorphy: Tubulocristate protist with double cone of microtubules arising from anterior pair of basal bodies. |
