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 two types of plankton: tiny plants--called phytoplankton, and weak-swimming animals--called zooplankton. Some are babies that will grow into strong-swimming, non-planktonic adults. Others will remain plankton for their entire lives.
