Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Raios dorsais (total) : 8; Raios anais : 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
Índice de diversidade filogenética (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).
Nível Trófico (Ref.
69278): 2.0 ±0.2 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (28 of 100).
