Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 20 - 21; Rückenflossenweichstrahlen (insgesamt) : 7 - 8; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 6 - 7; Wirbelzahl: 28 - 29. Diagnosis: relatively deep-bodied species with a steep, straight forehead (Ref. 42983, 52307) and short snout (Ref. 52307). Very flat gibbosity, most pronounced in adult males; lower pharyngeal bone with 151 teeth (mean value); usually 5 broad gill rakers on lower limb of first arch (Ref. 42983).

Inhabits clear flowing water with rocks, in river pools; found in small groups, up to 20 individuals (Ref. 42983). Likely a pair-bonding, cave-spawning species (Ref. 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [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).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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