Organisms categorized within the genus Pleurosigma appear all over the world, regardless of location.  The genus is one of the larger groups of diatoms, containing hundred of different species and also making it very difficult to identify exact taxonomy of organisms.

Thallasiothrix microscopic view

 

 

From Phyto’pedia Length (apical axis): 10 – 110 μm
Width (transapical axis): 2 – 4 μm
Height (pervalvar axis): 3 – 8 μm
Marginal areolae: 10 – 12 in 10 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).

We see these often in the summer in the lower intertidal zone. Their yellow egg cases also show up on the underside of rocks. They have a sharp penetrating tongue with which they can penetrate the shells of other molluscs
