Early development of the flathead,Percophis brasiliensis (Teleostei: Percophididae), from Southeastern Brazil

Morphological and osteological development of the flathead,Percophis brasiliensis, is described based on specimens collected from southeastern Brazilian waters. Identification of larvae was based on pigment pattern and meristic counts. Distinct melanophores were present on the bottom of the hindbrain, between the bases of the pelvic fins and on the bases of the pectoral fins. Within the family Percophididae onlyPercophis brasiliensis has 57 myomeres, which result in the larvae having an elongated body form. The larval pigment pattern and structure of the caudal complex suggest that the subfamilies Percophinae and Bembropinae are phylogenetically close, while the Hemerocoetinae belong to an advanced group within the family.
