[2] It is found in freshwater habitats as plankton, and is distributed around the world.

[1] Dicloster acuatus is a colonial alga, consisting of coenobia of two or four cells, attached at their centers (in four-celled colonies, the two pairs of cells are arranged in different levels).

[1] Reproduction occurs asexually by the formation of autospores, with each cell forming up to four coenobia.

[1] Because of its coenobial morphology resembling genera such as Scenedesmus or Selenastrum, it has been placed in the families Scenedesmaceae and Selenastraceae at points.

However, analysis of 18S ribosomal RNA and ITS2 sequences have shown that it is more closely related to genera such as Parachlorella in the family Chlorellaceae.
