twice eye diameter; gill opening preceded anteromedially by a small lappet-like fleshy protuberance;
rear margin of orbit above rictus; cephalic pores developed, SO 1+3, IO 4+2, POM 6+3, and ST 3
present; teeth conical, developed, uniserial in jaws and vomer; coloration brown, median fins white,
anal-fin membrane black posteriorly; vertebral formula 30.3/62.7/182.3, total vertebrae 182 or 183 (Ref. 92848).

Bayesian length-weight: a=0.00076 (0.00029 - 0.00199), b=3.06 (2.84 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.3 ±0.8 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
