Eastern Pacific Ocean: from the Gulf of California and southwestern tip of Baja California northward to Bahia Santa Maria. Former subspecies D. pectoralis fallax (Mexico to Ecuador, including Cocos Island) and D. pectoralis insulatus (Revillagigedo Islands) in Ref. 11482 were elevated to species level.

Short description Identification keys | Morphology | Morphometrics

Distinguished from D. fallax and D. insulatus by having the following characters: scales absent above the lateral line; upper lip fimbriae, modally 9; preopercular canal pores, modally 5; unbranched labial fimbriae (Ref. 82814).

Found on sandy bottoms near reefs (Ref. 37955). Feeds on small fishes and invertebrates (Ref. 11482). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 20.6 - 28.4, mean 24.7 °C (based on 56 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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): 4.0 ±0.61 se; based on food items.

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