deskripsi pendek Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)): 0; duri punggung lunak (Keseluruhan (total)): 8-11; Duri dubur 0; Sirip dubur lunak: 9 - 11. Diagnosis: dorsal fin origin behind pelvic fin origin; 96-104 lateral line scales; preanal length 70.7-76.2% SL; prepelvic length 46.7-52.6% SL; 9-11 anal fin rays (Ref. 26644). Lower lobe of caudal fin longer and narrower than upper lobe in fully adult males (Ref. 26644, 27292), the upper lobe as long as the proximal part of the caudal fin (Ref. 27292). Opercular disc of males characteristic, its posterior margin broad, and postopercular apparatus well developed and pillow-like (Ref. 26644).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [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).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
