Etymology: Pseudoscaphirhynchus: Greek, pseudes = false + Greek, skaphe = boat + Greek, rhyngchos = snout (Ref. 45335).

Species of the genus Pseudoscaphirhynchus belong to the subfamily Acipenserinae, and not Scaphirhynchinae as it was previously considered (V. Birstein, pers. comm. 03/05 ).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00138 - 0.00693), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (46 of 100).
