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.
Spectacular phytoplankton blooms are found in cooler waters where nutrients are brought up from the sea floor during storms. Marine animals are divided into three groups: zooplankton (those that float), nekton (those that actively swim) and benthos (those that live on or in the ocean bottom).
