Pleurosigma pacificum is a species of planktonic diatom discovered in the tropical Western Pacific Ocean.
Pleurosigma pacificum is a naviculoid diatom, a type of photosynthetic protist (or alga) that is similar in shape to those of the genus Navicula, said to be shaped like a boat.[2] In particular, naviculoid diatoms of the genus Pleurosigma usually have a sigmoid valve or raphe, in the shape of a sigmoid function or the letter S.[3] The species P. pacificum is characterized by lanceolate valves, around 45.0–51.1 μm long and 13.0–15.6 μm wide, that taper gradually towards subacute ends. Their raphe is straight, filiform, slightly curved near the poles. The center of the valve is round, while the terminal area is shaped like a funnel.[1]
