is a suitable particular species for genetic studies on nearly scaleless skin, transparency and high sensitivity to hypoxia stress. Here, we generated a high-quality chromosome-level de novo assembly of . The final de novo assembly yielded 379.47 Mb with 28 pseudo-chromosomes and a scaffold N50 length of 14.52 Mb. In total, 21,074 protein-coding genes were predicted. , and had formed a clade, which diverged about 115.5 million years ago. In the air exposure stress experiment, we found that some genes play an essential role during hypoxia, such as , , , and in the circadian rhythm pathway. These genomic data offer a crucial foundation for ecology and adaptation studies, as well as a deeper understanding of the response to air exposure stress.
是进行近无鳞皮肤、透明度和对缺氧应激高敏感性遗传研究的合适特定物种。在此，我们生成了高质量的染色体水平的从头组装。最终的从头组装产生了379.47 Mb，包含28条假染色体，支架N50长度为14.52 Mb。总共预测了21,074个蛋白质编码基因。 、 和 形成了一个分支，大约在1.155亿年前分化。在空气暴露应激实验中，我们发现一些基因在缺氧期间起着至关重要的作用，例如昼夜节律途径中的 、 、 、 和 。这些基因组数据为 生态学和适应性研究提供了关键基础，也有助于更深入地了解对空气暴露应激的反应。
