Facultative air-breathing (Ref. 126274); Occurs in quiet areas of streams, sloughs, swamps and other wetlands over mud and debris (Ref. 5723, 10294). Often found in dense vegetation. Tolerates drought, low oxygen levels and extremes water temperature (Ref. 5723). Feeds on aquatic insects, amphipods, isopods, and snails (Ref. 10294).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6329 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00468 (0.00186 - 0.01174), b=3.14 (2.92 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.7 ±0.2 se; based on diet studies.

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Fec = 1,500; K=0.3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).

Price category (Ref. 80766): Unknown.
