Morphology | Morphometrics
Has 13 pectoral rays and maybe confused with P. russellii. Median fish are almost clear, but become spotted in large adults. It is best identified by the pale-centered scales on the principal dark bands on the body forming a net-like pattern and V-like markings across the pectoral fin rays (Ref. 48635).
On rocky substrates in subtropical waters. Usually found on open substrates with remote outcrops of reef or soft-bottom substrates at moderate depths (Ref. 48635). Feeds on fish and crustaceans. Spines are venomous.
