Short description Identification keys | Morphology | Morphometrics

The species differs from three of the four other congeneric species (L. affinis, L. macrops and L. retropinna) by having a distinct gap between the posterior ends of the dorsal and anal fins and the beginning of procurrent caudal finrays. This gap is absent in the three species mentioned, but present in the fourth (L. lubricum), from which L. macrophthalmum differs by having a lack of dermal papillae along the lateral line, pectoral fins lower on body, a larger eye relative to head dimensions, and a shorter pre-dorsal length (Ref. 86873).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00163 - 0.00737), 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): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
