Chroococcus turgidus is a type of cyanobacteria characterized by spherical cells that frequently form colonies. Each cell is enveloped in a mucilaginous sheath that aids in aggregating cells into clusters. Typically small, these cells range in diameter from approximately 2 to 10 micrometers. Found in freshwater habitats like lakes, ponds, and slow-moving streams, Chroococcus turgidus contributes to aquatic ecosystems through photosynthesis and participation in nutrient cycling.
