Inhabits rivers of low to high current velocity and stagnant waters between sea level and 100 m elevation, generally occurs in freshwaters but sometimes in slightly brackish river mouths. More abundant near the coast and only large individuals are found upstream. Benthic species that lies waiting for prey, shrimps and fish under stones or overhanging shorelines (Ref. 36880).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00495 - 0.01398), b=3.12 (2.97 - 3.27), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.65 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
