Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi anali molli: 29 - 33. Dactyloscopus heraldi differs from Dactyloscopus byersi in a number of features: no scalation above the curved portion of the lateral line (vs. one row); A 29-33, modally 32 (vs. 31-35, modally 34); upper lip fimbriae 11-14, modally 12 (vs. 13-18, modally 15); preopercular sensory pores increases in number with size, but more present in D. byersi of comparable sizes; chevron markings weak or absent (vs. prominent on the side posteriad) and presence of dark bars on the dorsum (vs. absent) (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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), 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).
