簡短描述 檢索表 | 型態特徵 | 形態測量圖

This species is distinguished from its congeners by the following characters: head profile with bump (specimens >162.5 cm TL); chin with enlarged bump (>135.0 cm TL); rectangular body scales on the middle region of the body (shape developing with age, final shape not established on specimens <70.0 cm TL, but established on those >162.5 cm TL; rounded clavus (usually not wavy and without indents), supported by 14-24 (mode 17) clavus fn rays and 8-15 (12) ossicles (Ref. 117083).
紫色垂直條由大約 16個鰭條支撐了, 那一個 12 有小骨。 小骨靠攏在一起, 比間隔的空間寬許多他們 (參考文獻 12900).

生物學特性     字彙 (例如 epibenthic)

This species is presumed to prefer warmer water temperatures than Mola mola (in Sanriku coast of Japan, this species occur at sea surface temperatures of 16.8-25.6°C, average 19.9°C (vs. 11.5-25.6°C, average 17.7°C when Mola mola appeared in the area). The maximum recorded weight of 2,300 kg applies to a 272 cm TL female caught off the coast of Kamogawa, Japan by a set net (Ref. 117083).
