Dash-like melanophores along anterior surface of gut; distinguished from C. pallasi by: lack of posteroventral pigment on gut; distinguished from Engraulis mordax by: dorsal and anal fin placement (6-8 myomeres between fins). Pigmentation: row of melanophores along dorsal surface of gut and along ventral midline; melanophores over anterior gut appear dash-like, and those over posterior gut become larger and more intense with development. Sequence of fin development: caudal, dorsal, anal, pelvics, pectorals. |
