The Japanese rice fish or medaka is a model organism in genomic and experimental biology and was the first vertebrate animal to mate in space, during the mid-1990s. As their name suggests Japanese rice fish can be found in flooded rice paddies in Japan, Taiwan, and other areas of southeast Asia.

Japanese rice fish have a short gestation period and reproductive characteristics that make them easy to rear in the laboratory. They also have many attributes that make them a model organism for scientific study, such as the clarity of its eggs, hardiness and lack of aggression. They have clearly defined sex chromosomes, unlike zebrafish, and in comparison with zebrafish it are hardier and less prone to disease. They are also more closely related to the fugu (Takifugu and Tetraodon).

The Medaka genome has been sequenced using whole-genome shotgun sequencing to give 10.6X coverage. It consists of approximately 700 Mb of sequence, on 24 chromosomes, giving almost 20,000 protein-coding genes. The species-specific sequence evidence (medaka cDNA and protein) is very limited, so the majority of gene models are based on genewise alignments of proteins from other species that are genetically distant to medaka.
