Short description Identification keys | Morphology | Morphometrics

Dactyloscopus elongatus is distinguished from Dactyloscopus fimbriatus by several features: including number of upper lip fimbriae 13-17, mean 15.0 (vs. 15-19, mean = 17.4); number of segmented anal-fin rays 38-41, modally 39 (vs. 36-39, modally 37); number of preopercular canal pores mean = 8.6 (vs. 14.8); some body proportions; coloration with weak to no markings (vs. distinct) (Ref. 82814).

Estimates based on models

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): 4.2 ±0.6 se; based on size and trophs of closest relatives

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