Morphology | Morphometrics
soft rays: 48;
Vertebrae: 60. This speciesi differs from L. affinis, L. macrops, L. retropinna by having a distinct gap between the posterior ends of the dorsal and anal fins and the origins of the upper and lower procurrent caudal-fin rays; differs from L. lubricum by lacking dermal papillae along the lateral line, by having pectoral fins low on body (vs. high) with 6 fin rays (vs. 7-8), and having fewer caudal-fin rays 16 (vs. 17-18); differs L. macrophthalmum by having a longer pre-dorsal length 54.9% SL (vs. 49.3%), fewer pectoral-fin rays 6 (vs. 8), fewer pelvic-fin rays 5 (vs. 8) and longer dorsal- and anal-fin rays (vs. shorter); differs from its congeners by having fewer pre-ural vertebrae 60 (vs. 64-84) (Ref. 113803).

Phylogenetic diversity index (Ref. 82804
= No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00339 (0.00162 - 0.00710), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 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.).
Fishing Vulnerability (Ref. 59153
