Pelagomonas
Pelagomonas is a genus of heterokont algae. It is a monotypic genus and includes a single species, Pelagomonas calceolata[1][2] which is a unicellular flagellate organism, an ubiquitous constituent of marine picoplankton.[3][4] It is an ultra-planktonic marine alga.

Description
Pelagomonas calceolata is uniflagellate, about 1.5 × 3 μm in size. Microtubular roots, striated roots and a second basal body are absent. A thin organic theca surrounds most of the cell. There is a single chloroplast with a girdle lamella and a single, dense mitochondrion with tubular cristae. A single Golgi body with swelled cisternae lies beneath the flagellum, and each cell has an ejectile organelle that putatively releases a cylindrical structure. A vacuole, or cluster of vacuoles, contains the putative carbohydrate storage product.[4]
