Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 2; Mjukstrålar i ryggfenan (totalt): 6; Taggstrålar i analfenan 0. Diagnosis: first or second branched ray of dorsal fin longest but always shorter than head (comprised from 3.5 to 4.5 times in standard length), never filamentous; base of adipose fin shorter than, or equal to, dorsal fin base; 9-13 (often 10-11) gill rakers on lower limb of first gill arch; pectoral fins with 8 (sometimes 9) branched rays; like most other species of the genus, C. teugelsi shows a sexual dimorphism between mature males and immature specimens (Ref. 57126).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00471 - 0.02328), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
