portrait amoeba
Tetramitus (tet-rah-might-us) is one of the heterolobose amoebae, which can be found as amoebae, flagellates or cysts. The amoebae produce their pseudopodia suddenly, a pattern of behaviour referred to as eruptive as opposed to the more usual slow progressive formation of pseudopodia. With file filaments making up the posterior uroid. Contractile vacuole located at the posterior end of the cell. 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.

Tetramitus
From the collection
American Type Culture Collection
| Description of Tetramitus: With four equal flagella arising in a flattened slit at the front end of the cell, surrounded by a distinct anterior lip-like rostrum. Substantial fibrous root associated with flagellar bases. Cysts without pores. Many of the flagellates assigned to this genus are likely to be more closely related to Percolomonas cosmopolitus than to T. rostratus, the type of this genus. Reported from soil, freshwater and faeces. |
