Description
Size: Pervalvar axis 3-45 μm; diameter 8-130 μm.

Color: Yellow brown.

Paralia sulcata cells are cylindrical and wider than long. Cells are heavily silicified. They are united into chains of varying length by marginal linking spines and interlocking ridges and grooves on the flat valve face. The linking structures are visible in water mounts. Two types of valves occur: separation valves which lack the linking spines, and linking valves. External openings of the strutted processes can be seen as granules in light micrographs (LM). The numerous chloroplasts appear as small discs in LM.

Reproduction is general for group: both sexual and asexual.
