Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 12 - 16; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 16 - 19; Ryggkotor: 55 - 57. Jaw extends to posterior margin of the eye; eye is small; head displays a dorsal bulbous swelling behind eye, particularly in large individuals; caudal peduncle elongated. Principal caudal fin rays 11-13. Caudal fin rounded (Ref. 43717).

Facultative air-breathing in the genus (Ref. 126274); Inhabits ephemeral areas that dry out over summer and autumn months, where it aestivates in damp areas or under tree roots and logs (Ref. 43717).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00206 - 0.01165), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

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