Etymology: Petrotilapia: Latin,petra = stone + Bechuana, African native thiape = fish (Ref. 45335);  palingnathos: The name palingnathos, from the Greek pálin, meaning back or backwards, and gnáthos, meaning mouth or jaw, referring to the shorter lower jaw; a noun in apposition (Ref. 87181).

Short description Morphology | Morphometrics

Dorsal spines (total): 17 - 18; Dorsal soft rays (total): 8-10; Anal spines: 3; Anal soft rays: 7 - 8. Diagnosis: Adult male and female Petrotilapia palingnathos have distinctly retrognathous jaws and can thus be distinguished from all other members of Petrotilapia (Ref. 87181). Furthermore, the absence of a dark submarginal band in the dorsal fin distinguishes P. palingnathos from P. microgalana, P. genalutea, P. nigra, P. chrysos, P. mumboensis, and P. pyroscelos, which have such a band (Ref. 87181). Adult males of P. palingnathos are dark gray with orange markings and scales outlined in blue with orange cheek and a blue gular area, which distinguishes them from P. tridentiger, which are light blue with dark blue bars, and from males of P. xanthos which are yellow, while those of P. flaviventris are yellow on ventral and mid-sides with scales outlined in blue (Ref. 87181).

Biology     Glossary (e.g. epibenthic)

Normally found in the shallow but not wave-washed habitat (Ref. 87181).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
