The Complete Genome Sequences of three species from the killifish genus (Rivulidae, Cyprinodontiformes).

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.
