Blepharisma (Figs. 1A and 1B) is a genus of ciliate protozoans in which most of the 47 listed species contain a pink pigment named blepharismin that renders them sensitive to glass-transmitted visible and nearultraviolet (UV) radiation. Initially, the pigment was called zoopurpurin by Arcichovskij (1905), who first determined its absorption spectrum. The name was changed to blepharismin to conform to the terminology of hypericin-like pigments, using the genus name as the basis of nomenclature: hypericin from Hypericum, stentorin from Stentor, fabrein from Fabrea, and blepharismin from Blepharisma (Giese, 1973).
