Occurs over sandy and rocky bottoms. Has a very protractile mouth which allows it to dig in the sand for organisms on which it feeds. Oviparous (Ref. 205). The juveniles are often found in tributaries which may be very distant from the main river beds (Ref. 12225).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00363 - 0.03629), b=2.93 (2.68 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
