      "text": "美丽硬骨舌鱼（亚洲龙鱼）\n来自远古的骨舌鱼类\n美丽硬骨舌鱼属于骨舌鱼目骨舌鱼科，\n主要分布于东南亚热带淡水河流、湖泊\n和沼泽环境中。其身体修长，覆盖大型鳞\n片，鳞片表面具有明显光泽；口部上翘，\n具有一对须，能够捕食鱼类和昆虫等。骨\n舌鱼类是一支古老的辐鳍鱼类，在中生\n代已经出现，并保留了一些早期硬骨鱼\n类的形态特征。现生骨舌鱼类为认识早\n期分化真骨鱼类的形态与生态特征提供\n了重要的比较材料。\nScleropages formosus(Asian Arowana)\nAn Ancient Lineage of Bony-Tongue Fishes\nThe Asian arowana belongs to the order Osteoglossiformes and \nthe family Osteoglossidae. It inhabits tropical freshwater \nenvironments in Southeast Asia, including rivers, lakes, and \nswamps. Its elongate body is covered with large, lustrous scales. \nThe mouth is upturned, and a pair of barbels is present at the tip \nof the lower jaw. It feeds on fishes, insects and other small \nanimals. Bony-tongue fishes represent an ancient lineage of \nray-finned fishes that first appeared during the Mesozoic and \nretain several morphological features of early bony fishes. Living \nbony-tongue fishes provide important comparative material for \nunderstanding the morphology and ecology of early-diverging \nteleost lineages.",

The exceptionally preserved fossils \nfrom Xiangxiang, Hunan Province, and Songzi, Hubei \nProvince, provide important evidence for understanding \nthe evolutionary history of arowanas. Research \nindicates that the divergence between the genus \nScleropages and the South American osteoglossid \ngenus Osteoglossum can be traced back to \napproximately 56 million years ago. This discovery \nextends the evolutionary history of living arowanas into \nthe Early Cenozoic and provides important clues for \nunderstanding the intercontinental distribution patterns \nand biogeographic history of bony-tongue fishes.",
