Telonemia

Telonemia are a phylum of microscopic eukaryote, single-celled organisms.[1] They are protists and are suggested to have evolutionary significance in being a possible missing link between ecologically important heterotrophic and photosynthetic species.^[1] [2]

According to Kamran Shalchian-Tabrizi from the University of Oslo’s Centre for Ecological and Evolutionary Synthesis, "this new group of organisms may have a greater genetic diversity than all known genomes of mammals, fish, birds, and reptiles".^[2] [3] Telonemia eat other single-cell organisms and planktonic algae, and in turn is eaten by animal plankton. "We are convinced that this group plays a central role in the ocean’s food chain and is a fragile piece of the greater ecological interplay,” says professor Kjetill S. Jakobsen.[4]

Telonemia species eat other living cells, and thus might be useful in understanding basic cell biology.[5]
