Algae

​Planktonic Algae:  Millions of floating plants that color pond water green to blue and even brown or red. Many species are involved in algae blooms and these species change over time based on temperature, light, nutrients, and other factors.

 

 

 

Filamentous Algae: Single algae cells that form filaments that intertwine creating a mat that resembles wet wool. Filamentous algae starts growing along the bottom in shallow water or attached to structures in the water (like rocks or other aquatic plants). Often filamentous algae float to the surface forming large mats, which are commonly referred to as Pond scum or moss.
