Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 1; Mjukstrålar i ryggfenan (totalt): 6; Mjukstrålar i analfenan: 19 - 22; Ryggkotor: 41. Diagnosed from Trachycorystes trachycorystes by having the following characters: jaws equal in length (vs. lower jaw longer, prognathous in Trachycorystes trachycorystes); skull roof covered by thick integument concealing bony sculptures (vs. skull roof covered by thin integument, bony sculptures visible); inner mental barbel thin and very short, not reaching base of outer mental barbel (vs. inner mental barbel thicker, extending to or beyond base of outer mental barbel); dorsal-fin spine serrated only along posterior margin (vs. dorsal-fin spine serrated only along anterior margin); caudal fin weakly forked (vs. emarginate); gas bladder simple, without diverticula (vs. gas bladder with three posterior diverticula, one medial and paired posterolateral) (Ref. 87314).

Biologi     Ordlista (t.ex. epibenthic)

Found in abundance in tributaries of the rio Aripuanã, such as igarapé do Aeroporto and igarapé Genipapo, clear water creeks two or three m wide and up to 0.6 m deep, with forested margins and sandy bottoms where fallen trunks, branches and vegetal detritus were abundant. Collected using deep nets and by displacing the submerged debris, the natural hiding-places of the species. Feeds on fish, various insects as well a scorpion and a crustacean (Ref. 87314).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.4   ±0.4 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 (14 of 100).
