Occur in swamps and mud-bottomed and heavily vegetated ponds, lakes and sloughs (Ref. 5723, 10294). Young feed primarily on small crustaceans (ostracods, amphipods, etc.), midge larvae, and small dragonfly nymphs; adults' diet is similar but also contain snails, aquatic hemipterans and terrestrial insects (Ref. 10294).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00598 - 0.02533), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (tmax=3).
Fishing Vulnerability (Ref.
