The large cell size (16 X the biomass of Chaetoceros and 3 X the biomass of Tetraselmis) extends the algae feeding period until the end of the PL stage.  During the winter this algae is about 15 microns, but shrinks to about 5 microns during the summer.

The color of TW varies from brown to green to yellow, depending on the amount of chlorophyll in the culture. This color change does not in any way affect the quality of the algae.

Note: this algae will slowly change in color from brown to a light green after a few weeks in storage. This is caused by a change in the chlorophyll and has no effect on the quality of the algae.
