Chaetoceros debilis

Chaetoceros debilis are centric diatoms that are 8-40 um wide, that connect into twisted chains. The ends of the cell walls are either flat or slightly concave with rounded corners. The spaces between the cells appear almost rectangular and slightly compressed. The spines start from inside the cell and extend outwards.

Chaetoceros debilis's distribution is cosmopolitan in cold waters.
