Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 11; Spine anali: 1; Raggi anali molli: 10. Diagnosis: Distinguished from its congeners in having 15-16 pectoral fin-rays (vs. 18); cephalic lateralis pore P absent (vs. present); head, nape, ventral abdomen, and dorsal midline of caudal peduncle naked (vs. scaled); and caudal peduncle with a large, black blotch (vs. none) (Ref. 56733).

Small, sand-diving gobioids; inhabits drop-off with caves and ledges, silty sandy shelves and slopes, with hydroids, sea fans and a variety of hard corals and some Halimeda (Ref. 56733).

Estimates based on models

Preferred temperature (Ref. 123201): 27.2 - 29.1, mean 28 °C (based on 22 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [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): 3.1 ±0.4 se; based on size and trophs of closest relatives

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