Pseudorasbora pugnax is a species of cyprinid fish endemic to Honshu, Japan. [1] [3]
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna up to the Atlantic bluefin tuna, which averages 2 m (6.6 ft) and is believed to live up to 50 years.
The Penang betta is a species of gourami native to Southeast Asia and common in swiftly flowing forest streams of the Malay Peninsula, Thailand, Sumatra, and the Riau Islands. In addition to its native range, the species has been introduced to Guam. It can be found amongst the vegetation growing along the banks. This species can reach a length of 6.7 centimetres (2.6 in) SL. It is one of the mouthbrooding Betta species. This species, as a natural predator of mosquito larvae, has found use in mosquito control efforts. Prior to its being eclipsed in Western public recognition by the mass-imported B. splendens, B. pugnax was well known as a fighting fish, as denoted by the specific epithet of pugnax, attracting the interest of scientists studying animal behaviour at least as long ago as the 1880s.
The Japanese sawshark is a species of sawshark in the family Pristiophoridae. This shark has a long, narrow rostrum. Its first dorsal fin originates behind the tips of the pectoral fins, and its caudal fin is angled almost straight in line with the body. The Japanese sawshark reaches a maximum length of up to 1.36 m.
The Japanese topeshark is a species of houndshark, in the family Triakidae. It can reach a length of up to 1.1 m. It is found in the subtropical northwest Pacific from China, Taiwan, Korea, and Japan, between latitudes 40° N and 21° N.
The salamander shark or salamander catshark is a little known catshark that inhabits a range from Japan and the East China Sea, on the upper to middle continental slope at depths of 358–895 m. Specimens of this species can attain a total length of at least 64 cm. This catshark is a potential bycatch of trawl fisheries operating within its range, but no details are available. There are high levels of squalene in this catshark's liver. The reproduction of this catshark is oviparous.
The Japanese catshark is a catshark of the family Scyliorhinidae, found in the northwest Pacific off Chiba Prefecture, Honshū, Japan, between 36 and 34°N. This shark has a relatively slender body, with the trunk tapering towards the head. Its snout is moderately long, bell-shaped, and broad; the preoral snout is about 7 to 8% of total its length. It has large gill slits, rather small eyes in adults, nostrils fairly broad, and a long broad, arched mouth. It is commonly taken by trawl off the type locality, and possibly used for oil, human consumption, and fishmeal or fish cakes locally.
Rhodeus smithii, sometimes known as the Japanese rosy bitterling, Japanese bitterling, or Nippon baratanago is a temperate freshwater fish belonging to the Acheilognathinae subfamily of the family Cyprinidae. It originates in stagnant waters in inland rivers in Japan. It was originally described as Achilognathus smithii by Charles Tate Regan in 1908, and is also referred to as Rhodeus ocellatus smithii in scientific literature.
The Yanbaru whiskered bat(Myotis yanbarensis) is a species of vesper bat in the genus Myotis.
The deepbody bitterling or Itasenpara bitterling is a species of freshwater fish in the family of Cyprinidae. It is endemic to central and southern Japan. It grows to a maximum length of 8.0 cm.
The ariakehimeshirauo, Neosalanx reganius, is a species of icefish in the family Salangidae endemic to Japan. It is only known from Midori and Chikugo Rivers in Kyushu. Its maximum total length is 63 mm (2.5 in), and has a lifespan of about one year. It seems to be relatively rare in its limited habitat, and is classified as an endangered species by IUCN.
The stone moroko, also known as the topmouth gudgeon, is a fish belonging to the Cyprinid family, native to Asia, but introduced and now considered an invasive species in Europe and North America. The fish's size is rarely above 8 cm and usually 2 to 7.5 cm long.
Betta is a large genus of small, active, often colorful, freshwater ray-finned fishes, in the gourami family (Osphronemidae). The best known Betta species is B. splendens, commonly known as the Siamese fighting fish and often kept as an aquarium pet.
Pseudorasbora is a genus of small freshwater fish native to eastern Asia, including China, Korea, Japan and Siberia. P. parva, has been introduced to regions outside its native range and is considered invasive.
The Japanese lates, also known as the akame or Japanese barramundi, is a species of fish found in Japan. A bottom-dweller restricted to estuarine habitats and large rivers in the Pacific coastal western parts of the country, it is threatened by habitat destruction. As it is similar to the related barramundi, it was classified as the same species until 1984.
The Japanese Spanish mackerel, also known as the Japanese seer fish, is a species of true mackerel in the scombrid family (Scombridae). Their maximum reported length is 100 cm, and the maximum reported weight is 10.57 kg.
Gobioninae is a monophyletic subfamily of Eurasian cyprinid fishes. A species-rich subfamily, it is divided into five tribes: Gobionini, Pseudogobionini, Hemibarbini, Coreiini, and Sarcocheilichthyini.
The Tokyo bitterling is a temperate freshwater fish of the carp family (Cyprinidae). Taxonomically, it belongs to the subfamily Acheilognathinae.
Fedorov's catshark is a catshark of the family Scyliorhinidae. This shark has oviparous reproduction. This is a very poorly known species, with less than 30 specimens reported in the scientific literature. Almost nothing is known of its biology. This species may be endemic to northern Japanese waters, where it is taken in water around 1,200 m deep. However, accurate identification of Apristurus species is particularly difficult, and further research is required to determine its geographical and bathymetrical distribution.
Pseudorasbora elongata is a species of cyprinid fish found in the Li River and lower reaches of the Yangtze in China.
