Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 14 - 17; Anal spines: 0; Anal soft rays: 13 - 15; Vertebrae: 65 - 69. Lateral line straight (Ref. 27547). Pelvic fins with small axillary process; caudal slightly indented (Ref. 27547). Deep velvet black on back and sides, paler below; small bright red spots on back and sides, spots smallest and most numerous on back; largest spots smaller than pupil of eye; some or all spots may be surrounded by a blue to pale halo; leading edges of dorsal, anal and pelvic fins cream to yellow; all rayed fins dark, without spots or marks; adipose fin paler than rayed fins, with a dark posterior margin (Ref. 27547).

Biology     Glossary (e.g. epibenthic)

Found only in small headwater streams (Ref. 27547). In the winter, it congregates in flowing streams (Ref. 27547). Reported to spawn in the spring (Ref. 27547).

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=0.00977 (0.00473 - 0.02021), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax=3-10).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
