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.

由于潜在的敌对行为和难以捉摸的栖息地，海鳗（Muraenidae）作为全球珊瑚礁中的一组顶级掠食者尚未得到充分研究。在这里，我们为代表性的里夫氏海鳗（ Gymnothorax reevesii ）构建了染色体水平的基因组组装。该单倍型基因组组装长度为 2.17 Gb，97.87% 的序列锚定在 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%有功能注释。这个测序的鳗鱼目海洋物种很好地补充了鳗鱼基因组的遗传资源。它不仅为里夫海鳗的深入研究提供了遗传资源，而且可以实现各种鳗鱼之间的深入基因组比较。
