Department of Oceanography, Inha University
The morphological study of C. oculus-iridis was performed based on cultured and net samples with light microscope and scanning electron microscope. The samples were collected in Inchon coastal waters and cultured with F/2 media. Cell shape is coin or disk shape, valve face flat and slightly depressed in central area. Cingulum has 2-3 copulae and ligula band. Heterovalve structure which has hyaline area and central rosette in the central area of two valve was sometimes observed. Areolae size are equal or variable with the size of valve. Eye spot was observed on the areolae. Cribra morphology is variable during the valve formation. The foramina is circular with developed rim. The micro-labiate process and macro-labiate process of fan-shape were observed in marginal ring.
Key words: morphology, Coscinodiscus oculus-iridis, cribra, rosette, labiate process
