Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 16; Raggi dorsali molli (totale) : 11; Spine anali: 3; Raggi anali molli: 8. Differs from P. fenestratus and P. taeniolatus in the more specialized form of the jaws, with the dental arch of the premaxilla narrow anteriorly, but spreading laterally at the posterior ends, with rather long anterior teeth, and in the enlargement of the pharyngeal teeth.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Individuals at Nkomo Reef were observed to occur over sand and scattered rocks at a depth of about 17 m. Feeds from the rocks and small pebbles of the environment and also from the zooplankton when this is available (Ref. 5595).
