Short description Identification keys | Morphology | Morphometrics

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).

Biology     Glossary (e.g. 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).
Trophic level (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).
