Short description Morphology | Morphometrics

<>Semotilus corporalis can be distinguished by the possession of the following characters: large eye; large lateral scales (43-50); moderately compressed body; fairly long, rounded snout slightly overhanging large mouth; dorsal fin origin over or slightly behind pelvic-fin origin; 8 dorsal rays; 8 anal rays; adults have scales on backs and upper side darkly outlined; and young has black stripe along side, dark caudal spot. Olive to gold-brown above, dark stripe along back; bright silver side, sometimes with purple or blue sheen; black bar along back of gill cover. Breeding males have fairly large tubercles on head (Ref. 86798).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00468 - 0.01779), b=3.12 (2.96 - 3.28), based on LWR estimates for species & (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.55 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (55 of 100) .
