[4][13][14] The taxonomic position of certain populations, including some in China, Laos and east Korea, is unclear and require further study. [7] They can survive in a wide range of water temperatures (3–42 °C or 37–108 °F), but they prefer a water temperature of 15–28 °C (59–82 °F). [46] In 2006, it was found that a transgenic line of medaka was brought to Japan from Taiwan for commercial purposes. Haploid embryonic stem cell lines have been established.[23]. It is euryhaline, occurring in both brackish and freshwater. On the other hand, the northern population was derived from a population from the Tajima-Tango region and spread alongside the Sea of Japan coast. Oryzias latipes is a model organism and is extensively used in many areas of biological research, most notably in toxicology. Mad Father. 135 offreg 468 0 mao.5ch . [27][28] In 2014, work began on generating 111 different inbred lines derived from a single population collected in the wild.[29]. Based on morphology it is closer to O. sakaizumii than O. latipes, but it may be an undescribed species. O. latipes returned to space in 2012, launched aboard a Soyuz spacecraft Soyuz TMA-06M and housed in an aquarium aboard the International Space Station.
