Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 10-11; Afterflossenstacheln 0; Afterflossenweichstrahlen: 9; Wirbelzahl: 33. Possess a tubular gonopodium with shortened second, fourth and fifth anal fin rays, an enlarged seventh middle anal fin radial in males and females, and an elongate dorsoposterior process of the lacrimal. Branchiostegal rays: 5. Distinguished from other Plesiojenynsia by the following combination of characters: a single midlateral stripe without associated dorsolateral or ventrolateral stripes or blotches in adults; a terminal to slightly oblique mouth; fewer than 13 gillrakers; and absence of the first mandibular-canal pore.

Commonly found in upland rivers. Viviparous (Ref. 45800).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00517 - 0.02671), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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