Morphology | Morphometrics
Barbel with medial branch arising from stem and a pair of lateral branches arising from medial branch distal to its origin; medial branch stout, almost as thick as stem, terminating in rounded tip lacking filaments; lateral branches tiny, short filaments; terminal bulb protruding strongly dorsad, ovoid in lateral profile; three long medial terminal filaments on distal end of bulb; a pair of dorso-lateral terminal filaments terminating in small but prominent spheroids (Ref. 45801).

Estimates based on models
Preferred temperature (Ref. 115969
): 7.7 - 18.4, mean 11.5 °C (based on 75 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.5 ±0.80 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (31 of 100) .
