Etymology: Schistura: Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335); waltoni: Named for J. Walton.
Eponymy: Joseph Walton (1817–1898) was an American naturalist, botanist and a contributor to the fish collection at the Academy of Natural Sciences of Philadelphia in its early history. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 12; Anal soft rays: 8. A member of the group of species with complete or nearly complete lateral line, 8 1/2 branched dorsal rays, 9+8 branched caudal rays and no sexual dimorphism. Can be distinguished by the following characters: caudal peduncle 0.84-1.11 times longer than deep, its length being 12.4-14.7% SL, 58-71% HL and its depth 12.9-14.8% SL, 58-73% HL; 9-12 bars (Ref. 39226).

Occurs in small mountain streams with fast and shallow water. Feeds on insects and invertebrates, based on the stomach contents of a 5.46 cm SL specimen. Juveniles were observed to form loose troops of 10-20 individuals (Ref. 39226)

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=0.00692 (0.00310 - 0.01545), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

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