Reproductive ecology of Pterapogon kauderni, an endemic apogonid from indonesia with direct development

Pterapogon kauderni does not have secondary sexual dimorphism, and has an equal sex ratio (50.8% males:49.2% females). Females first mature at a length of about 34mm. Data from both laboratory-bred and wild-collected eggs and embryos are not consistent with the presence of differential reproductive...
