Phytoplankton of the month — November 2019

Odontella aurita

Odontella aurita cells join in straight or zig-zag chains, connecting with mucous pads on either one or both elevations. Odontella aurita are 10-97μm wide at their apical axis, and have numerous small chloroplasts. These cells have short external labiate processes, differing from Odontella longicruris which has long external tubes extending past neighboring cells. Odontella aurita are cosmopolitan.
