Description
Cells are elongated, slightly asymmetric and narrow toward the posterior end. Cells are solitary, or sometimes form two- and four-celled chains. The cells are brownish-yellow in color, and parallel sides toward the anterior, a blunt extension at one side, the presence of thecal plate pores and knob-like spines on the surface of the thecal plates, and a rounded nucleus located in the posterior region of the cell. The chloroplast is visible in the center and along the margins of the cell. The V-shaped periflagellar area is visible on the right thecal plate, and the thecal pores are randomly distributed near the periflagellar area. The periflagellar area of Prorocentrum obtusidens consists of seven platelets bearing the wing-like structure and two platelets without the wing-like structure, one flagellar pore, and one accessory pore.
