Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 34; Radios blandos dorsales (total) : 48 - 56; Radios blandos anales: 46 - 60; Vértebra: 79 - 80. Distinguished from all other Mastacembelus (sensu Travers) by substantially lower counts of dorsal and anal fin rays and vertebrae. The dorsal rays only 48-56 and anal fin rays only 46-60 (other Mastacembelus with dorsal and anal rays usually 70 or more). Vertebrae 79-80 (others species usually with 85 or more). The caudal fin rays count 21-22 is high (Mastacembelus alboguttatus, M. dayi and M. unicolor are the only other species with as many or more caudal fin rays. Snout very broad and short; jaws extending posteriorly fully two-thirds of distance to below anterior margin of eye; preorbital spine extending posteriorly to below margin of eye or somewhat beyond; preopercle without spines; body with a few large dark spots which may extend onto base of dorsal fin, fins otherwise plain (Ref. 39392).

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=0.00269 (0.00128 - 0.00564), b=2.94 (2.76 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
