🐟 Physical Description

Dorsal soft rays (total): 7; Anal soft rays: 15; Vertebrae: 42. Distinguished from its congeners, except for P. fumosus and P. moeschii, by the presence of an enlarged and prominent process of the post-temporal (the "supraclavicular process" of previous authors), which is almost as long as the post-cleithral process; the presence of long hair-like epithelial projections on the skin and long tubular extensions of the sensory pores. Differs from P. fumosus and P. moeschii in having a pointed (vs. rounded) tip of the nuchal shield. Can be further distinguished from P. fumosus in having less developed procurrent caudal rays that are evenly sloping along the anterior edges (vs. well developed that curve sinuously along the edges) and from P. moeschii in having a deeper body (13.0-16.7% SL vs. 13.0-14.5) and lacking lighter colored patches on the body . : elongated.
