Short description Bestämningsnycklar | Morfologi | Morfometri

Differs from Umbra pygmaea by the lack of dark blotch at caudal base, its body and head irregularly strewn with small dark sport, and having 33-35 scales in midlateral series (Ref. 59043).

Biologi     Ordlista (t.ex. epibenthic)

Facultative air-breathing (Ref. 126274); Adults inhabit small irrigation canals and slowly flowing and stagnant waters with dense vegetation (Ref. 26183), usually in small ditches, oxbows, backwaters and shallow lakes (Ref. 59043). Territorial in shallow pools and swamps. They feed on larger crustacean plankton and invertebrate larvae (Ref. 26183). This species is under threat due to habitat destruction, irrigation works and disappearance of shallow ditches as suitable habitats, restrictions of river inundation, pressure from introduced fish species and chemical pollution (Ref. 26183).

Bayesian length-weight: a=0.01023 (0.00411 - 0.02546), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.3   ±0.39 se; based on food items.
Generation time: 1.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
