Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 8.9 cm SL male/unsexed; (Ref. 116588)

Short description Morphology | Morphometrics

Dorsal spines (total): 10 - 11; Dorsal soft rays (total): 12-13; Anal spines: 3; Anal soft rays: 11 - 12; Vertebrae: 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).
Trophic level (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
