Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 38.0 cm TL male/unsexed; (Ref. 86798)
soft rays: 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. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00453 - 0.02909), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
Climate Vulnerability (Ref. 125649
