Due to potentially hostile behaviors and elusive habitats, moray eels (Muraenidae) as one group of apex predators in coral reefs all across the globe have not been well investigated. Here, we constructed a chromosome-level genome assembly for the representative Reeve's moray eel (Gymnothorax reevesii). This haplotype genome assembly is 2.17 Gb in length, and 97.87% of the sequences are anchored into 21 chromosomes. It contains 56.34% repetitive sequences and 23,812 protein-coding genes, of which 96.77% are functionally annotated. This sequenced marine species in Anguilliformes makes a good complement to the genetic resource of eel genomes. It not only provides a genetic resource for in-depth studies of the Reeve's moray eel, but also enables deep-going genomic comparisons among various eels.
由于可能存在敌对行为和难以捉摸的栖息地，海鳝（Muraenidae）作为全球珊瑚礁中的顶级掠食者之一，尚未得到充分研究。在这里，我们为具有代表性的波纹裸胸鳝（Gymnothorax reevesii）构建了染色体水平的基因组组装。这个单倍型基因组组装的长度为 2.17 Gb，序列中有 97.87%锚定在 21 条染色体上。它包含 56.34%的重复序列和 23,812 个蛋白质编码基因，其中 96.77%具有功能注释。这种在鳗鲡目中测序的海洋物种是鳗鲡基因组遗传资源的很好补充。它不仅为深入研究波纹裸胸鳝提供了遗传资源，还使各种鳗鱼之间能够进行深入的基因组比较。
