Coloured scanning electron micrograph (SEM) of Prorocentrum micrans, marine thecate dinoflagellate. Prorocentrum micrans, marine dinoflagellate. Prorocentrum micans is an armoured, marine, bloom-forming dinoflagellate (algae). It is a cosmopolitan planktonic species in cold temperate to tropical waters. Prorocentrum species produce okadaic acid, which is associated with diarrheic shellfish poisoning (DSP). Dinoflagellates are unicellular protozoans. About 90% are found in marine environments as plankton. They are characterised by the presence of two flagella (not visible). One flagellum beats back and forth, while the other is flat and ribbon- like, and works as a rudder to steer and rotate the organism. Magnification: x465 when shortest axis printed at 25 millimetres.
