The killifish genus currently contains seven recognized species found in freshwater and mangrove microhabitats in South and Central America, the Caribbean, and Florida. species have several unique features. Beyond its amphibious nature, two of the species ( and Costa 2011) are the only known vertebrates capable of self-fertilization. Although reference genomes for self-fertilizing species are readily available, a complete understanding of the genomic basis leading to the transition in mating systems in the genus requires more genomic resources at a broader taxonomic level. Here, we present the complete genome sequences for three species from Brazil: the endangered freshwater species and and the androdiecious but obligate outcrossing ( Costa 2011). The raw data and assembled genomes are available in GenBank.
鳉鱼属目前包含七个已确认的物种，分布于南美洲、中美洲、加勒比地区和佛罗里达州的淡水和红树林微生境中。这些物种具有几个独特的特征。除了其两栖特性外，其中两个物种（Costa 2011）是已知仅有的能够自我受精的脊椎动物。尽管自我受精物种的参考基因组很容易获得，但要全面了解导致该属交配系统转变的基因组基础，还需要在更广泛的分类水平上有更多的基因组资源。在这里，我们展示了来自巴西的三个鳉鱼物种的完整基因组序列：濒危淡水物种和以及雌雄同体但 obligate outcrossing（Costa 2011）。原始数据和组装好的基因组可在GenBank中获取。 （注：原文中“androdiecious but obligate outcrossing”这里“obligate outcrossing”可能有误，不太明确准确意思，按原文翻译了）
