Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 1; Mjukstrålar i ryggfenan (totalt): 6; Mjukstrålar i analfenan: 11 - 15. Body elongated, without scales but with a range of 33-35 spiny bony plaque which runs along the length of the lateral, starting from the extreme end of the caudal fin up to the point directly below the origin of the dorsal fin. Head is pointed and laterally compressed, its width being far less than its length. Eyes are high and are situated in the posterior half of the head. Mouth is inferior, provided with a pair of maxillary barbels branching into 12 or 13 branches and 4 short mandibular barbels. Adipose fin short

Can emit sounds by moving its pectoral spines. Every basic unit of sound emitted lasts for 60-70 millisecond, with a frequency of 60-90 Hertz corresponding to the reply frequency of the muscles utilized (Ref. 35381).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00437 - 0.01992), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 2.8 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).
