Navicula is a genus of boat-shaped algae — primarily aquatic, eukaryotic, photosynthetic organisms, ranging in size from a single cell.
Navicula is a diatom. The Navicula genus of diatoms comprises over 1,200 species.[1] Navicula is Latin for "small ship", and also a term in English for a boat-shaped incense-holder.[2]
Navicula play an important role in global ecology, producing about a quarter of all the oxygen within Earth's biosphere and serving as keystone species in the food chain of many environments where they provide a staple for the diets of many aquatic species.
Mobility
Navicula diatoms are known for their ability to creep about on each other and on hard surfaces such as microscope slides.[3] [4] [5] [6] It is thought that around the outside of the navicula's shell is a girdle of protoplasm that can flow and thus act as a tank track.
