Etymology: Sicyopterus: Greek, sika, sikya = cucumber + Greek, pteron = wing, fin (Ref. 45335);  squamosissimus: The specific name alludes to the high numbers of scales compared to its congeners having two lateral clefts on crenulated upper lip, a second dorsal fin I10 and second and third rays of the first dorsal fin filamentous.

Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 10. Sicyopterus squamosissimus is distinguished by having two lateral clefts on crenulated upper lip, a second dorsal fin with one spine and 10 segmented rays, filamentous second and third rays of the first dorsal fin, 61-66 lateral scales, 21-26 predorsal scales and 17-22 transverse back scales, and a reddish caudal fin in male with a slight blue line on the upper and lower parts (Ref. 106177).

Biology     Glossary (e.g. epibenthic)

Occurs in small, rapid and boulder-strewn mountain streams with rocky bottoms with two other Sicydiinae, Sicyopterus lagocephalus (Pallas, 1770) and Stiphodon semoni Weber, 1895 (Ref. 106177).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 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 (14 of 100) .
