Skeletonema costatum (Greville) Cleve is a chain forming and a cosmopolitan diatom species that is well-known for its unique hallmark, the intercalary processes that joint and integrate two valves forming a suture line (Hasle & Syvertsen 1997). There are typically 3–4 areolae between each process (Hasle and Evensen 1975, 1976, Paasche et al.
