FIGURE 2 in Taxonomic consideration of eight Chinese bisexual Artemia populations, based on the morphology of frontal knob and gonopod and the result of cross-breeding tests

FIGURE 2. SEM photographs of the frontal knobs of Chinese bisexual Artemia populations to show the appearance of frontal knobs (A, C, E and H; frontal view) and the arrangement of spines (B, D, F, G and I). (A, B) SIN. (C, D) BDJR. (E, F, G) YIM (arrows in F point to spines arranged in a pattern of sextuplet; G is an enlarged image of a cluster of spines in septuplet pattern). (H, I) JYH. Abbreviations of Artemia populations see Table 1. Scale bars: A, C, E and H = 100 µm; B, D, F and I = 20 µm; G = 10 µm.
