Short description Identification keys | Morphology | Morphometrics

Has broad dark bands that are distinct when juvenile but break up in large individuals (Ref. 48635).

Caught at great depths; ca 100 m on sandy gravel bottom (Ref. 11230, 48635). Often caught by trawls. Used in Chinese medicine (Ref. 12166).

Estimates based on models

Preferred temperature (Ref. 123201): 21.7 - 28.2, mean 27.3 °C (based on 106 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00038 (0.00024 - 0.00061), b=3.25 (3.12 - 3.38), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.65 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
