Protoperidinium, dinoflagellate
By Nic Christ


Protoperidinium are dinoflagellates that can be found throughout the world’s coastal ocean at about the size fifty to one hundred micrometers. They have a diamond shaped cell that acts as strong armor and is made of a series of plates where their flagellae come through (Johannesson et al 2000). The flagella is what gives the protoperidinium the ability to swim.

They play an important role in the food chain, the serve as predators as well a prey. They eat small organisms like diatoms and are fed on by plankton like copepods (Evagelopoulos 2002).
