Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 559)
Adults pair and feed in loose groups; juveniles gather in small groups on deep sand slopes, usually in current-prone areas (Ref. 48635). Occurs in mud bottoms 15-100 m deep (Ref. 90102). Commonest member of the Japanese cepolid fishes. Caught by trawl net from sandy or muddy bottoms. Used mainly for fish cake. (Ref. 559 and 637). Minimum depth of 15 m reported from Ref. 90102.

Estimates based on models
Preferred temperature (Ref. 115969
): 20.2 - 26.6, mean 24 °C (based on 40 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00230 - 0.01199), b=2.82 (2.61 - 3.03), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (42 of 100) .
