      "text": "多鳍鱼\n早期辐鳍鱼类的现生遗存\n多鳍鱼是现生辐鳍鱼类中较早分化的\n代表类群之一，保留了许多独特的形态\n特征，如菱形硬鳞、背部由多个小鳍组\n成的背鳍，以及能够辅助空气呼吸的肺\n样结构。这些特征为研究早期辐鳍鱼类\n的身体构型、生态适应和演化历史提供\n了重要线索。\nPolypterus\nA Living Relict of an Early-Diverging Actinopterygian Lineage\nBichirs (Polypterus) are among the earliest-diverging lineages \nof extant ray-finned fishes and retain several distinctive \nmorphological features, including rhomboid ganoid scales, a \ndorsal fin composed of multiple separate finlets, and paired \nlungs used for air breathing. These features provide important \nclues to the body plan, ecological adaptations, and \nevolutionary history of early actinopterygians.",
