Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 7 - 9. Diagnosis: Distinguished from other cyprinids except Notropis buccatus by having a modified infraorbital and preoperculomandibular canals. It differs from N. buccatus by possessing longer gill rakers (length to width average 2.2, 4.8-2.5 vs. 1.0, 0.8-1.4), absence of breast squamation (vs. with scales), and possessing 5 infraorbital ossicles (vs. 4) (Ref. 57709).

The species occurs in small schools, often in clear, shallow (up to 50 cm) streams in slow to moderate runs; prefers sandy to sand mixed with gravel substrates (Ref. 57709).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00395 - 0.01919), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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