Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 18 - 19; Rayons mous dorsaux (Total): 9-10; Épines anales 3; Rayons mous anaux: 7 - 8. Diagnosis: Petrochromis horii differs from its congeners with no overlaps in several morphological characters: its body is deeper than that of Petrochromis macrognathus; the caudal peduncle is deeper than that of P. orthognathus; the pectoral fin is longer than that of P. macrognathus; the pelvic fin is longer than that of P. fasciolatus; the caudal fin is longer than that of P. famula, P. fasciolatus and P. orthognathus; the interorbital region is wider than that of P. macrognathus and P. orthognathus; the upper jaw protrudes more than that of P. fasciolatus and less than that of P. macrognathus, P. polyodon and P. trewavasae; the soft rays in the dorsal fin are fewer than in P. macrognathus; and the number of scales in longitudinal line is larger than in P. famula and P. orthognathus (Ref. 95531).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [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).
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
