Abstract

Thyrsitops lepidopoides larvae were caught with Bongo nets in the upper 200 m of the ocean from the coast of southern Brazil during 1975-1978. Based on a serie of 271 specimens ranging from 2.5 to 24.0 mm body lenght, morphological and osteological development of the larvae and juveniles is described. Small larvae (2.5-12.0 mm NL) can be distinguished from all known gempylid larvae by the presence of a distinct melanophore at the base of the dorsal and anal fins. The larvae have well developed dorsal and ventral spines. It is the only gempylid with six preopercular spines and non-serrated dorsal and ventral spines during the larval stage.
