संक्षिप्त वर्णन
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 17 - 18; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 8 - 10; गुदा कांटा: 3; ऐनल सौफट रेज़: 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).
Body shape (shape guide): fusiform / normal.
Normally found in the shallow but not wave-washed habitat (Ref. 87181).
