簡単な記述 検索表 | 形態学 | 形態計測学

背面の脊椎 (合計) : 0; 背鰭 (合計) : 15 - 16; 肛門の骨: 0; 臀鰭: 12 - 23. Belly sharply keeled. No distinct silver stripe along the flank and the first (anterior) supra-maxilla minute or absent (cf. Platanichthys platana). Distinguished from very similar R. arcuata of coastal waters by having fewer dorsal and pectoral fin rays and fewer gill rakers total; from small Sardinella and Harengula by the evenly rounded hind margin of the gill opening.
