      "text": "文昌鱼\n脊索动物活化石\n文昌鱼体长约50毫米，身体侧扁、半透\n明，两端尖细，外形似鱼，但没有明显的\n头部、头骨和脊椎。其脊索沿身体背侧\n纵贯全身，并一直延伸至体前端。文昌\n鱼保留了脊索、背神经管和咽鳃裂等脊\n索动物的基本身体结构，是研究脊索动\n物身体构型及脊椎动物早期演化的重\n要现生参照。\nBranchiostoma\nA Living Fossil of the Chordates\nBranchiostoma is a small, translucent marine \ncephalochordate about 50 mm long. Its body is laterally \ncompressed and tapers at both ends, giving it a fish-like \nappearance. However, it lacks a distinct head, cranium, \nand vertebral column. Instead, a notochord extends nearly \nthe full length of the body and reaches its anterior tip. It \nalso retains key features of the basic chordate body plan, \nincluding a notochord, a dorsal hollow nerve cord, and \nnumerous pharyngeal slits. As a living representative of \nCephalochordata, Branchiostoma provides an important \ncomparative reference for understanding the chordate \nbody plan and the early evolution of vertebrates.",
