Salpingoeca huxleyi Ellis, 1930. Cell globular. Body of lorica egg-shaped, with a wide, sturdy neck which bulges towards its own base. This neck appears to be marked off, at its actual base, from the lorica proper by a costa-like ring. This ring is probably an optical effect due to the lorica neck being set in a shallow depression or in-fold of the lorica body. A further peculiarity is that the neck of the cell is never extended beyond the distal limit of the lorica neck, so that the base of the collar is always within its everted rim. Collar and flagellum normal. Nucleus conspicuous. Contractile vacuoles: two. Peduncle length variable. Length of body of lorica: 8 microns Length of neck of loriea: 4 microns Width at centre of neck of lorica: 3 microns Greatest width of lorica: 6.5 microns Peduncle length: 16-32 microns This is one of about 700 species of heterotrophic flagellates reported from marine environments.

Salpingoeca huxleyi
From the collection
Heterotrophic flagellates of marine habitats
| Description of Salpingoeca huxleyi: The colonies are tree-shaped, composed of dichotomously branched tubes. Each branch of the colony usually consists of four tubes. The cells are about 6 microns long and they are located each in one tube at the distal end of the branches, with their flagella emerging out of the matrix. Due to the form of the tubes, the cells are cylindrical in shape. A single layer of closely spaced small matrix spherules separates the cells and forms the surrounding tube. A thin layer of mucilage lines the inner surface of each tube. The flagella are about 6 microns long and move only in a slight vibration. A single contractile vacuole lies medially and laterally. |
