Korte beschrijving
Morfologie | Morfometrie
Dorsale stekels (totaal): 3; Dorsale zachte stralen (totaal): 6; Wervels: 34. Scorpiodoras calderonensis differs from its congeners S. heckelii and S. liophysus by having secondary gas bladder terminally extended by elongate diverticulum 'recurved like the whip of a scorpion' (vs. secondary gas bladder absent in S. liophysus and without elongate terminal diverticulum in S. heckelii). It is further distinguished from S. heckelii by having a relatively small eye, diameter 63-93% of interorbital width (vs. relatively large eye, diameter 91- 129% of interorbital width) and from S. liophysus by possessing relatively shallow scutes, depth 41-59% of body depth near anal-fin origin (vs. 61-72%) (Ref. 86601).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 2.3 ±0.1 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
