简单描述 型态特徵 | 形态测量图

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).
紫色垂直条由大约 16个鳍条支撑了, 那一个 12 有小骨。 小骨靠拢在一起, 比间隔的空间宽许多他们 (参考文献 12900).

生物学特性     字汇 (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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6562   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02455 (0.01018 - 0.05918), b=3.02 (2.81 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
