Synopsis

We examined the gonads of eight species in five genera of hawkfishes. Histological preparations of ovaries and testes produced evidence for protogynous hermaphroditism inNeocirrhites armatus and suggested that hermaphroditism may also be expressed inCirrhitichthys oxycephalus, C. aprinus andC. falco, and possibly also by other species. Sexual patterns in hawkfishes are discussed in relation to environmental and ecological factors which influence mobility and length of spawning season.
