Short description
Claves de identificación | Morfología | Morfometría
Radios blandos dorsales (total) : 8; Radios blandos anales: 8. Lateral line with 51-83 scales, usually fewer than 70. Dorsal and anal fin usually with 8 rays. First gill arch with 9 or fewer rakers. Scales often darkly outlined (Ref. 86798).
Occurs in pools and undercut banks of creeks and small rivers, usually near woody debris. Also found in marshes. Maximum length is presumably about 38 cm TL (Ref. 86798).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00455 - 0.02896), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 2.0 ±0.2 se; based on size and trophs of closest relatives
Resiliencia (Ref.
120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (28 of 100).
