Microbial arms race: Ballistic "nematocysts" in dinoflagellates represent a new extreme in organelle complexity [PDF]

open access: yes, 2017
We examine the origin of harpoon-like secretory organelles (nematocysts) in dinoflagellate protists. These ballistic organelles have been hypothesized to be homologous to similarly complex structures in animals (cnidarians); but we show, using structural,
