Teleostei (teleosts) > Gonorynchiformes (Milkfishes) > Kneriidae (Shellears)
Etymology: Kneria: From Kner, that studied fishes in the Imperial Museum of Vienna, with Jean Natterer (1817) (Ref. 45335); uluguru: Named for the Uluguru Mountains, Tanzania, where the fish have first been collected; a noun in apposition (Ref. 26644).
Eponymy: Dr Rudolf Kner (1810–1869) was an Austrian zoologist specialising in ichthyology. [...] This is a toponym referring to the Uluguru Mountains in Tanzania, where the species appears to be endemic. (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 10; Anal spines: 0; Anal soft rays: 9 - 11. Diagnosis: small species with long head, 18.8-25.0% SL; snout relatively long, 28.6-37.0% SL, with narrow cleft and peculiar structure of the inferior positioned mouth; opercular disc of males shallow, with rounded outer edge; pectoral fin long, 14.9-17.7% SL; preanal length relatively short, 65.0-71.9% SL; 79-87 lateral line scales, which tends to increase with increasing length of the fish; distinct blackish streak from tip of snout to caudal fin, which may be coverd by dark bluish spots; dorsal fin origin clearly behind pelvic fin origin (Ref. 26644).

Maximum total length recorded is 5.31cm TL; inhabits clear streams and rivers with very fast current to more gentle waterflow, but more numerous in the quieter stretches; omnivorous, but feeds mainly on algae and aufwuchs rasped off from stones; apparently no marked spawning season (Ref. 26644).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

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