Short description Morfologi | Morfometri

Diagnosis: broad black band on outer edge of anal fin (especially in the much-smaller females); anterior dorsal fin rays extremely short, sometimes barely visible, more elongated in posterior portion; caudal fin in males somewhat lanceolate, although upper parts may possess elongated rays, giving it a lobe-like appearance; caudal fin more rounded in females; dorsal, anal and pelvic fin rays can be extremely elongated in males (Ref. 52307). Coloration: body bluish-gray, sometimes turquoise in the most anterior parts; snout, throat and breast slightly orange in some specimens; males with dark margins on body scales and well-developed rows of maculae on dorsal, anal and most of the caudal fin (save for the thin white margin on the upper edge); ripe females with red to violet belly that becomes extremely swollen immediately prior to spawning; large, white genital papilla always visible (Ref. 52307).

Cave-spawner (Ref. 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

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): 3.2 ±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 (10 of 100).

Price category (Ref. 80766): Unknown.
