We describe aspects of the life history of the small cardinalfish Ostorhinchus rubrimacula from a single, large collection taken at Koro, Fiji. We determined size at maturity and batch fecundity, examined otolith microstructure to construct a vonBertalanffy growth curve, described a length-weight relationship, and performed a dietary analysis. Ostorhinchus rubrimacula is a gonochore that mature...

Groupers of the family Epinephelidae are a diverse and economically valuable group of reef fishes. To investigate the evolution of their mitochondrial genomes we characterized and compared these genomes among 22 species, 17 newly sequenced. Among these fishes we identified three distinct genome organizations, two of them never previously reported in vertebrates. In 19 of these species, mitochon...

Haemulidae species are morphologically diversified fishes with wondrous and changeable coloration. These species are prevalent in global tropical, subtropical, and temperate inshore reef areas. Previous morphological classification within Haemulidae and some related families was problematic, and no comprehensive molecular evaluation was conducted on these groups. In this study, we revealed the ...

A second species of Grammatonotzts from the Hawaiian Islands, tentatively identified as G. macrophthalmus Katayama, Yamamoto & Yamakawa (Callanthiidae), is recorded from French Frigate Shoals and the Northampton Seamount based on observations from a research submersible. In the absence of collected specimens, identification was made by comparing characters visible in video images with previousl...
