types of phytoplankton
Three main types of phytoplankton are: 1  Cyanobacteria (blue-green algae). 2  These are very small and difficult to study. 3  They may be found in large blooms - it is the color of a cyanobacteria that causes the name (and occasionally, color) of the Red Sea.
There are three main types of plankton: 1  Plant plankton, also known as phytoplankton – single-celled photosynthetic organisms which manufacture food using energy from sunlight. 2  Zooplankton – single-and many-celled animals that feed on live plankton.
