Teleostei (teleosts) > Siluriformes (Catfishes) > Loricariidae (Armored catfishes) > Hypoptopomatinae
Etymology: saxicola: From the Latin adjective saxicola, meaning living among the rocks, in allusion to the habitat where the species occurs (under the rocks of river bottoms).
Eponymy: Dr Isaäc J H Isbrücker (d: 1944) is a Dutch ichthyologist who is an expert on the taxonomy of South American armoured catfishes (Callichthyidae, Loricariidae). [...] (Ref. 128868), visit book page.

Found usually on the bottom among rocks and stones in a small creek flowing through a landscape of mixed open fields and riparian vegetation, sometimes with a very degraded margin. The stream has rocky bottom with small to medium-sized rocks, loose stones and gravel, sometimes with sand and mud on the small pools bottoms, and has clear to turbid and moderate to strong flowing water (Ref. 57731).

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=0.02138 (0.00778 - 0.05875), b=2.93 (2.70 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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