Morphology | Morphometrics
soft rays: 10. This species is distinguished by the following characters: the scales extend ventral to second dorsal fin along septum to hypural base, well-developed on caudal peduncle; mostly cycloid scales with a few ctenoid ones along midline; 19 pectoral rays; no conical teeth on lower jaw; spotted midlateral stripe slightly ventral to septum (Ref. 39342).
Collected above a series of waterfalls, together with Sicyopus discordipinnis and Stiphodon birdsong (Ref. 39342).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), based on all LWR estimates for this body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
