Trichamoeba cloaca
Trichamoeba cloaca, 96 µm

Trichamoeba cloaca Bovee, 1972

Diagnosis: L : B ratio up to 3. Locomotion slow compared to T. sinuosa; uroid often bulbous, ragged, with short (pseudo)villi; usually with up to 30 relatively large flattened or truncated bi-pyramidal crystals; nucleus with small nucleoli, most peripherally located.

Dimensions: length 80-150 µm, L:B < 3; nucleus 8-15 µm.

Ecology: freshwater; sediments.

Remarks: The locomotive form doesn’t show the typical zigzag movement, so characteristic for T. sinuosa.
