Carte 2 issued from : J.T. Turner in Mar. Biol., 1977, 40. [p.254, Fig.3]. Pontella meadi from estuarine waters near Galveston (Texas).
3: Fecal pellet produced on Skeletonema costatum plus Nitzschia sp. diet; 4: high magnification of area in square in 3.

Nota: Sinking rates of fecal pellets produced by the species, grazing on 4 different phytoplankton diets, ranged from 15 to 153 m/day, with a mean of 66 m/day.
In 1979, Turner (1979, p.249) points to that pellets were colonized by rod-shaped bacteria that became attached to the outside of the peritrophic membrane and were not of intestinal origin.
