Flounder-shaped head (pleuronectiformes) Osteichthyes of a head, because swimming is named like butterflies flying. Because of the head on one side of head with two fish, two fish are considered to be the line side by side, also known as flounder. There are 3 sub-orders, 9 families of about 118 genera and 538 kinds. Chinese-made 3 sub-orders, 8 families and 50 genera 134 species. The bottom of the sea are fish, its distribution and the environment, such as ocean currents, water depth and water temperature and other factors are closely related. If all the ocean along the equator west of warm broad types of Trinidad and Tobago; Yellow Sea and the Yellow Sea along the coast and there is strong cold cold water, more types of cold-warm; West Pacific South China Sea and other ice age were not strongly influenced, also many types. A few species, such as China flounder in China, Jiang flounder, narrow tongue sole, brown spots and other tongue sole third-line access to rivers and fresh water life can be. Qian suborder eye with the left or right in the head and ending about the same, both flounder, flounder characteristics. Body oblong; odd fin separation, the item back and dorsal fin begins at the front fin and anal spines; gills tectorial membrane separation. Deep gorge carved narrow without gills; birth Jian Division 1 now is 2 to 3. Flounder suborder of the eye at least the first dorsal fin above the odd fin separation and no fin spines, gills have a Deep Gap; often sphenoid wing, after the key bone, rib or muscle biting. There are round flounder Branch, Division spine flounder, flounder Branch, Division flounder, flounder flounder Division and Division 6 Division crown. Sole suborder no fin spines, fin interconnect or separate odd dorsal fin begins at the muzzle, weak or no pectoral fins, pelvic fins 2 to 6, the lateral line from 0 to 3, posterior margin of preopercle hidden within the skin, gill rakers small or No, no wing sphenoid, after key bones, ribs, muscle and vomer teeth biting, head first into the deformed spinal cord spine to spine between the spinal cord, the first with the first clock pulse spine long spines; have sole Branch and Division 2 Section tongue sole.

diexing mu Flounder-shaped head Pleuronectiformes; flatfishes Osteichthyes of a head, because of swimming like butterfly fly is named. Because the head with bits of fish two first side, is considered to be two fish side by side and line, also known as flounder. 9 Section 3 of about 118 sub-projects are 538 kinds. Chinese-made 3 sub-orders, 8 families 50 are 134 kinds. The bottom of the sea are fish, their distribution and the environment, such as ocean currents, water depth and water temperature and other factors are closely related. West along the equator, such as warm ocean wide all, types of Trinidad and Tobago; Yellow, Bohai Sea Yellow Sea coast and there is strong cold cold water, cold temperature of more categories; West Pacific South China Sea were not strongly influenced by glacial periods, there are many types. There are few species in China, such as China flounder, river flounder, narrow tongue sole, brown spots and other tongue sole third-line access to rivers and fresh water life can be. □ suborder eye with the left or right in the head and ending about the same, both flounder, flounder characteristics.

Deep gorge carved narrow without gills; birth □ Section 1 now is 2 to 3 (see the big mouth □). Flounder suborder of the eye at least the first dorsal fin above the separation of Church and without fin spines, gills, Gap has a deep furrow; often sphenoid wing, after the key bones, ribs, or muscles to the bone. A round flounder Branch, Division spine flounder, flounder Branch, Division flounder, plaice flounder Division and Division 6 Division crown. Sole suborder no fin spines, fin odd interconnection or separation, the dolphin's dorsal fin begins, weak or no pectoral fins, pelvic fins 2 to 6, the lateral line from 0 to 3, before the posterior margin of gill cover bone hidden within the skin, gill rakers small or No, no wing of sphenoid, after key bone, ribs, muscle and vomer teeth biting, first to head into a deformed spine marrow marrow between the spine, the first with the first clock pulse spine long spines; the sole subjects and tongue sole Division 2 Division.
