🐟 Physical Description

Dorsal soft rays (total): 27 - 31; Anal soft rays: 17 - 20; Vertebrae: 33 - 37. This species is distinguished from P. nemorosus and P. aquilus by the absence of fingerlike papillae along the dorsal margin of the hyoid arch and at the interhyal-posterior ceratohyal articulation and by having fewer dorsal-fin rays, 27-31 (vs. 30-33 in P. nemorosus and P. aquilus); has more anal-fin rays, 17-20 (vs. 15-18); differs from P. maderensis by the position of the dorsal-fin origin which is above orbit (vs. posterior to orbit in P. maderensis), single row arrangement of the jaw teeth except near symphyses (vs. multiple rows in P. maderensis) .: short and / or deep; Cross section: compressed.
