Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 8; Raggi anali molli: 9. Differs from other species of Pseudecheneis by the combination of following characters: 9-14 transverse ridges on the thoracic adhesive apparatus; wide and flat snout, with ratio of snout width at mouth corner to distance between pectoral fin base larger than 0.75; caudal peduncle depth 6.1-9.3% SL and 29.4-46.7% in length of caudal peduncle; four yellow spots on caudal fin which are isolated and not connected with each other; premaxillary tooth band semicircular with six or eight teeth along its outer edge; body covered with dense, rounded tubercles distributed irregularly; tubercles increasing in density gradually from occipital to caudal peduncle; and 33 (17+16), 34 (17+17) vertebrae (Ref. 74729).

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=0.00589 (0.00260 - 0.01333), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
