Genera

Caelestes is a phylum of eukaryotic microbes in the supergroup Disparia. The name is derived from the Latin word caelestis, which refers to heavenly entities. This alludes to the similarity in morphology of the two named genera in this phylum—Meteora and Solarion—to the shape of celestial bodies: a meteor and the Sun, respectively. Members of this clade are distinguished by the presence of a unique type of stalked extrusome bearing a unique structure called a celestiosome. Celestiosomes are used to pierce prey (generally bacteria) with a central filament, immobilizing it and allowing it to be drawn toward the cell.
