Phylogenetic relationships of rabbitfishes (the family Siganidae), ecologically important components as primary consumers in coral reef communities, were studied using mitochondrial cytochrome b gene and nuclear ITS1 (internal transcribed spacer 1) sequence analyses. The analyses of 19 out of 22 species known in the Western Pacific region revealed that(More)
Sparid fishes consist of approximately 115 species in 33 genera that are broadly distributed in tropical and temperate coastal waters. Although several phylogenetic analyses were conducted based on specific molecular markers, their classification remains unresolved. Here, we present the most comprehensive molecular phylogeny of the family Sparidae to date,(More)
Several groups of marine fishes and squids form mutualistic bioluminescent symbioses with luminous bacteria. The dependence of the animal on its symbiont for light production, the animal’s specialized anatomical adaptations for harboring bacteria and controlling light emission, and the host family bacterial species specificity characteristic of these(More)
Four species of the fish genus Pempheris are recognized for the Red Sea: P. adusta Bleeker, 1877; P. mangula Cuvier, 1829; P. nesogallica Cuvier in Cuvier & Valenciennes, 1831; and a new species P. tominagai. All are wide-ranging in the western Indian Ocean, and P. mangula has migrated via the Suez Canal to the eastern Mediterranean Sea. Morphological and(More)
Schindleria (Gobioidei, Schindleriidae), believed to include one of the smallest and youngest reproducing vertebrates, is broadly distributed in the Indo-Pacific Oceans, inhabiting coral reef lagoons. They are all characterized by a reduced larval-like form, such as a slender translucent and scaleless body. The three nominal species recognized in the genus(More)
Molecular characters may offer a useful alternative to confidently estimate the phylogenetic position of paedomorphic taxa otherwise difficult to place based on morphology because of the reduction or absence of characters in their larvae-like adult stage. Here, we sequenced the complete mitogenome of a remarkable undescribed marine paedomorphic clupeiform(More)
 The taxonomic status of three small [probably less than ca. 600 mm in the largest total length (TL)] and poorly known species, Trichiurus brevis Wang and You, 1992 and T. minor Li, 1992, both from South China Sea, and T. russelli Dutt and Thankam, 1966, from Bengal Bay, was reexamined. Trichiurus brevis and T. russelli, being valid species, are redescribed(More)
T he members of the pipefish genus Microphis Kaup, mostly found in estuarine or freshwater habitats in tropical and subtropical areas, were reviewed by Dawson (1984), who recognized five subgenera and 2t subordinate taxa. In Japanese waters, three species were recorded by Senou et al. (1995): Miclvphis ( Oostethus) brachyurus brachyurus (Bleeker, 1853), M.(More)
Evoxymetopon macrophthalmus sp. nov. is described on the basis of a single specimen collected off Okinawa Island, Ryukyu Islands, Japan. Among the two valid species of Evoxymetopon, the new species is more similar to E. poeyi in having the first dorsal-fin spine enormously large, compressed, and sword shaped. It differs from E. poeyi in having the upper(More)
Pempheris ufuagari sp. nov. is described based on 10 specimens, 143.9-196.8 mm in standard length, collected from Mi-nami Daito Island and Ogasawara Islands, which are oceanic islands of Japan. Pempheris ufuagari is characterized by a distinct black spot on the pectoral fin base, a bright yellow dorsal and caudal fin, and a blackish band on the outer margin(More)
