Short description
Identification keys | Morphology | Morphometrics
This species can be distinguished from all its congeners except for L. schomburgkii
by having a single to a small patch of platelets ventromedially from the insertion of the pectoral-fin spine and nowhere else ventrally, and from by having black spots in the dorsal fin (vs. no or white spots) and black bands in the paired and caudal fins (vs. bands absent) (Ref. 56920).
Facultative air-breathing in the genus (Ref. 126274)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00719 - 0.03336), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
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).
