Maturity: Lm ?  range ? - ? cm
Bottom feeders; mainly on crustaceans and other small invertebrates. Males with markedly enlarged olfactory organs at maturity. Leptocephalus larvae pelagic. Taken occasionally in deep bottom trawls (Ref. 12887).

Estimates based on models
Preferred temperature (Ref. 115969
): 8.8 - 12.4, mean 11.1 °C (based on 19 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (43 of 100) .
