Chaetoceros is a large, ecologically important genus of marine planktonic diatoms. While the vegetative cells of this genus grow under favorable growth conditions, many species also form resting spores to survive environmental stress. The morphology of these spores differs markedly from that of vegetative cells. This review summarizes the morphological characters of vegetative cells and spores of Chaetoceros species, in order to better understand the life cycle and ecological significance of this species.
