Kamera lens is a unicellular, flagellate organism and the only species in the genus Kamera. Though the species has been known for centuries, it is poorly understood. Its systematic position within the Eukaryota is uncertain.
Anatomy, nutrition and reproduction
Kamera lens is a free-living, swimming, heterotrophic organism. It is 6 to 7 by 2.5 to 3 micrometers on average ) and ovate, the base of both its long flagella is below the tip (subapical). There is only one nucleus. Ultrastructural characters are not known.
Taxonomy and history
The first valid description (as Monas lens) was published by Otto Friedrich MÃ¼ller in 1773. William Saville Kent placed itin the genus Heteromita in 1880. Edwin Klebs moved it to Bodo in 1892, but this was rejected by H.M. Woodcock, who removed the species from Bodo and made it the type species of Heteromastix. David J. Patterson and Michael ZÃ¶lffel found Woodcock's description to be insufficient and created the genus Kamera for Kamera lens in 1991. Kamera lens is a play on words using the original species epithet. Due to lacking ultrastructural or molecularbiological data the species' rank is uncertain, thus it is placed as incertae sedis in the Eukaryota.
