Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 7-9; Afterflossenweichstrahlen: 8 - 12; Wirbelzahl: 35 - 37. Body deep. Nuptial males with greatly elevated dorsal and anal fins and a distal black caudal spot, deeper than long or vertically oval. Anal fin, when depressed, reaches to or beyond caudal fin base.

Inhabits sand-bottomed and silt-bottomed pools and runs of headwaters, creeks, and small rivers, Usually occurs along undercut banks and debris (Ref. 86798). Reported maximum length is 6.5 TL (Ref. 86798).

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=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±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).
