Mussel is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval.
Bivalvia or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of aquatic molluscs that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-shells known as valves. As a group, bivalves have no head and lack some typical molluscan organs such as the radula and the odontophore. Their gills have evolved into ctenidia, specialised organs for feeding and breathing.
Lake Biwa is the largest freshwater lake in Japan. It is located entirely within Shiga Prefecture, northeast of the former capital city of Kyoto. Lake Biwa is an ancient lake, over 4 million years old. It is estimated to be the 13th oldest lake in the world. Because of its proximity to the country's historical capital Kyoto, references to Lake Biwa appear frequently in Japanese literature, particularly in poetry and in historical accounts of battles.
Callista chione, the smooth clam, is a rather large, temperate, marine, bivalve mollusc that inhabits sandy bottoms or with small pebbles in clean waters down to about 200 m from the British Isles to the Mediterranean. The shell can reach up to about 110 mm Ø, its outer side is smooth and ranges from light greenish creamy colour to medium brown, probably varies to match the background; the interior is white to soft pink. The concentric and radial growth lines are easily seen. Callista chione is edible, different dishes are prepared throughout the Mediterranean in Spain, Italy, France, the Balkan and the Maghreb countries.
Rhodeus amurensis is a temperate freshwater fish belonging to the Acheilognathinae subfamily of the family Cyprinidae. It originates in the Amur River and Lake Khanka in Asia, and is found in China and Russia. It was originally described as Pseudoperilampus lighti amurensis by B.B. Vronsky in 1967, and has also been referred to in scientific literature as Rhodeus lighti amurensis.
The Kyushu bitterling is a temperate freshwater fish belonging to the Acheilognathinae of the family Cyprinidae. It originates on Kyushu Island in Japan. It was originally described as Acanthorhodeus atremius by Jordan & Thompson in 1914. The fish reaches a size of up to 6 cm (2.5 in), and is native to freshwater habitats with a pH of 6.8 to 7.8, a hardness of 20 DH, and a temperature of 10 to 25 °C.
Light's bitterling is a temperate freshwater fish belonging to the subfamily Acheilognathinae of the family Cyprinidae. It originates in Russia and China, from the Amur River basin to southern China. It was originally described as Pseudoperilampus lighti by H.W. Wu in 1931.
Rhodeus pseudosericeus is a temperate freshwater fish belonging to the Acheilognathinae subfamily of the family Cyprinidae. It originated in the Namhan River system in the Gyeonggi-do and Gangwon-do provinces of Korea. It was originally described as Acanthorhodeus atremius by Jordan & Thompson in 1914. The fish reaches a length up to 6.1 cm (2.4 in). When spawning, the females deposit their eggs inside bivalves, where they hatch and the young remain until they can swim.
Rhodeus sciosemus is a subtropical freshwater fish belonging to the Acheilognathinae subfamily of the family Cyprinidae. It originates in inland rivers in Japan. It was originally described as Acanthorhodeus sciosemus by Jordan & Thompson in 1914. When spawning, the females deposit their eggs inside bivalves, where they hatch and the young remain until they can swim.
Rhodeus suigensis is a temperate freshwater fish belonging to the Acheilognathinae subfamily of the family Cyprinidae. It originated in inland rivers in Japan and the Korean peninsula. It was originally described as Pseudoperilampus suigensis by T. Mori in 1935, and has also been referred to as Rhodeus atremius suigensis in scientific literature. The species was listed as endangered in 1994 by the World Conservation Monitoring Centre, but in 1996 was relisted as "data deficient". When spawning, the females deposit their eggs inside bivalves, where they hatch and the young remain until they can swim.
Rhodeus uyekii is a temperate freshwater fish belonging to the Acheilognathinae sub-family of the family Cyprinidae. It originates in inland rivers in South Korea. It was originally described as Pseudoperilampus uyekii by T. Mori in 1935.
Acheilognathus rhombeus is a temperate freshwater fish belonging to the Acheilognathinae sub-family of the family Cyprinidae. It originates in Japan and the Korean Peninsula. It was originally described as Capoeta rhombea by Temminck & Schlegel in 1846. It is the type species for the genus Acheilognathus.
Freshwater bivalves are molluscs of the order Bivalvia that inhabit freshwater ecosystems. They are one of the two main groups of freshwater molluscs, along with freshwater snails.
The bitterling-like cyprinids form the cyprinid subfamily Acheilognathinae. This subfamily contains seven genera, although the Khanka spiny bitterling is often placed in Acheilognathus, and at least 75 described species to date. Over half of the species are in the genus Acheilognathus.
The flying gurnard, also known as the helmet gurnard, is a bottom-dwelling fish of tropical to warm temperate waters on both sides of the Atlantic. On the American side, it is found as far north as Massachusetts and as far south as Argentina, including the Caribbean and Gulf of Mexico. On the European and African side, it ranges from the English Channel to Angola, including the Mediterranean. This is the only species in the monotypic genus Dactylopterus. Similar and related species from the genus Dactyloptena are found in the Indian and Pacific Oceans.
The stone flounder is a species of flatfish in the family Pleuronectidae. It is a demersal fish that lives on sandy and muddy bottoms in coastal areas at depths of up to 150 metres (500 ft). Its native habitat is the temperate waters of the north-western Pacific, from Japan to the Kuril Islands, Sakhalin, Korea, northern China and Taiwan. It is oceanodromous and is found in salt, brackish and fresh waters. It can grow up to 50 centimetres (20 in) in length, and may reach 12 years of age. It was formerly classified in the now defunct genus Kareius.
Acheilognathus macropterus is a species of cyprinid fish native to China and northern Vietnam. It grows to a length of 27.5 centimetres (10.8 in) SL.
The Khanka gudgeon is a species of cyprinid, an East Asian freshwater fish that occurs from the Amur basin in Russia, through China, Mongolia and Japan, to Vietnam. It reaches up to 13.6 cm (5.4 in) in total length.
