WebDiatom is the common name for a major group of unicellular or (less commonly) colonial algae comprising the protist taxon Bacillariophyceae (or Bacillariophyta), characterized by unique cell walls of silica (hydrated silicon dioxide). Called a frustule, these cell walls usually consist of two overlapping and interlocking asymmetrical sides with a split evident … Webspecies of diatoms, whose taxonomy is based on the size, shape, and sculpturing of their siliceous cell walls (Smol, 2008). Furthermore, they have very fast migration rates, which means that they can colonize new habitats very quickly, and their short-lifespan enables them to respond rapidly to environmental change (Rühland et al., 2003). shane foo fighters
