Camera lens is a flagellate species and the only member of the camera genus. Although the species has been known for several centuries, very little research has been carried out on it and its systematic position is also uncertain.

Features and way of life

The cell is small (6–7 × 2.5–3 micrometers in average specimens) and ovoid, the two long flagella are attached below the tip (subapical). A pocket or furrow is missing at this point. There is only one nucleus. Ultrastructural features are not known.

The camera lens is a freely swimming, heterotrophic unicellular organism . It lives as a saprobiont and can also be detected in hay infusions . Kent observed clusters of spores of the species there in 1880 (see picture).

Systematics and research history

The first description of the species as Monas lens comes from Otto Friedrich Müller in 1773. William Saville Kent placed it in the genus Heteromita in 1880 . Edwin Klebs placed it in the genus Bodo in 1892 , which HM Woodcock contradicted, separated the species from Kent's Heteromita in 1916 and placed it in its own genus as Heteromastix lens . David J. Patterson and Michael Zölffel updated his inadequate description in 1991, using the generic name camera, which is unusual in combination with the specific epithet . In the absence of ultrastructural or molecular biological data, the species cannot be systematically placed safely and is therefore usually placed incertae sedis with the eukaryotes .
