| Description: Bacillaria Paxillifer This living colony of planktonic diatoms includes many individual cells joined by the slits in their valve faces, called raphes, which allow them to move. Thus linked, the cells slide against one another to alternately extend and contract the entire colony and move it with an accordionlike motion unique among the diatoms.
