Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 10 - 11; Raios dorsais moles (total) : 12 - 13; Espinhos anais: 3; Raios anais moles: 11 - 12; Vértebras: 26 - 27. This species is distinguished by the following set of characters: posterior end of maxilla is strongly hooked; membranes connecting maxilla and premaxilla and covering inner posterior part of dentary pale; D X-XI,12-13; A III,11-12; branched caudal-fin rays 11-13 (exceptionally 5); cheek and opercle are naked; oblique body-scale rows in longitudinal series 33-39; has a very long pelvic fins, 39.4-75.3% SL; with L. lemur, differs from congeners in lacking an inner premaxillary dark stripe and having fewer numbers of segmented dorsal and anal-fin rays and associated unbranched rays (Ref. 116588).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

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