Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Spine anali 0. Adults: 12.4-18.4 cm TL. Adult body proportions, as percentage of TL (based on ten specimens 12.6-18.4 cm TL): prebranchial length, 8.2-13.3; branchial length, 8.4-10.8; trunk length, 43.4-51.6; tail length, 28.8-35.3; eye length, 1.6-3.2; disc length, 4.1-6.1; urogenital papilla length, 16.0 (percentage of branchial length in a spawning male measuring 12.9 cm TL); trunk myomeres, 58-73. Adult dentition: supraoral lamina, 2-3 unicuspid teeth, usually 3; infraoral lamina, 5-7 unicuspid teeth; 4 endolaterals on each side; endolateral formula, typically 2-2-2-2 or 2-3-3-2, the first and fourth endolaterals may also rarely be unicuspid; 2-3 rows of anterials; first row of anterials, 1 or 5 unicuspid teeth; exolaterals absent; 1 row of posterials with 10-17 teeth, of which 0-12 are bicuspid and the rest unicuspid; transverse lingual lamina, 15-20 unicuspid teeth, the median one slightly enlarged; longitudinal lingual laminae each with undetermined number of unicuspid teeth. Velar tentacles in adults, 5-12, with tubercles; median tentacle shorter than the lateral ones immediately next to it; body coloration (preserved), ventral aspect whitish; oral papillae, 5-26 (Ref. 89241).

Biologia     Glossario (es. epibenthic)

Inhabits riffles and runs of clear streams. Ammocoetes larvae occur near weed beds and sand bars. Non-parasitic (Ref. 5723). Freshwater; adults from Crooked Creek, Oregon are sexually mature in mid-March (Ref. 89241).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00117 (0.00051 - 0.00272), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.7 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100) .
