Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 2. Diagnosis: caudal peduncle relatively long, its depth slightly larger than the horizontal distance between adipose and caudal fin bases (never twice as large); anterior edge of pectoral spine smooth, except for a few serrations distally; preorbital head length greater than maximum head depth (measured to end of supraoccipital process), lending the snout an elongate appearance; numerous small spots on body and fins; spots on head and flanks of equal size; interorbital distance 28-30% HL; orbital diameter (measured on rostro-caudal axis) more than 2 times in interorbital distance (Ref. 81642).

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00218 - 0.01265), b=3.09 (2.88 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Fonte Biblio. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Fonte Biblio. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100). 🛈

Parauchenoglanis longiceps (Boulenger, 1913)
