Biology     Glossary (e.g. epibenthic)

Prefers shallow and muddy waters in savannah-like areas, with water temperatures approaching 30°C during the dry season; also found in waters bordering forested areas; when stressed or disturbed, the species will hide in the mud, sometimes up to 30 cm deep; biparental, open substratum spawner (Ref. 52307). Maximum recorded TL was 6.5 cm (Ref. 5599).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec=500).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
