Pigment Diagnostics: Distinguished from other pleuronectids without pigment bands by: heavy pigment pattern. Distinguished from Pleuronichthys decurrens by: less finfold pigment
Diagnostic Characters: Distinguished from other pleuronectids without pigment bands by: heavy pigment pattern. Distinguished from Pleuronichthys decurrens by: less finfold pigment, precaudal vertebrae 12-13 (P. decurrens usually has 13-15), lack of pterotic spines
