From Phyto’pedia Length (apical axis): 10 – 110 μm
Width (transapical axis): 2 – 4 μm
Height (pervalvar axis): 3 – 8 μm

(Cupp 1943, Kraberg et al. 2010)
Commonly found in nutrient-rich upwelling regions (Abrantes 1988, cited in Kobayashi and Takahashi 2002). Its presence indicates conditions of high productivity (Schrader and Sorknes 1990, cited in Kobayashi and Takahashi 2002). Optimal temperature ∼15 °C (Resende 2007). Salinity range from ∼12 – 33 (Demir 2007, Burns 1977).
