Bacillaria paxillifer(or Bacillaria paxillifera) is a colonial diatom species in the family Bacillariaceae. [2] Bacillaria paxillifer is homotypic with Bacillaria paradoxa, but B. paxillifera is the correct name. [3]

Bacillaria have a unique form of colonial motility among diatoms. [3] Individual cells (with their long axes parallel to one another) slide against their neighbors in a coordinated fashion, allowing the entire structure to expand or contract. [4]

Taxonomy

Bacillaria paxillifer was originally described under the name Vibrio paxillifer by Otto Frederick Müller in 1786. It is the first diatom species known to be described. [5] It was separately described two years later (1788) by Johann Friedrich Gmelin as Bacillaria paradoxa. The correct name, Bacillaria paxillifera(O.F.Müll.) N.I.Hendey. (1951), was established based on rules of priority. [2] [5]
