Species

Navicula is a

algae, comprising over 1,200 species.[1] Navicula is Latin for "small ship", and also a term in English for a boat-shaped incense-holder.[2]

Diatoms — eukaryotic, primarily aquatic, single-celled photosynthetic organisms — play an important role in global ecology, producing about a quarter of all the oxygen within Earth's biosphere, often serving as foundational organisms, or keystone species in the food chain of many environments where they provide a staple for the diets of many aquatic species.

Mobility

Navicula diatoms have been observed to possess a motile ability to glide over one another and on hard surfaces such as microscope slides.
