Introduction Antarctic marine invertebrates have struggled to survive in extreme environmental conditions and have evolved to possess specialized life strategies. Thus, extant species in the Antarctic have received considerable attention for studying adaptation mechanisms and other fundamental biological knowledge of extremophiles. However polar organisms haven't been developed as the laboratory species because of the difficulties of the accessibility and cultivation of them. As most biological research has long relied on a small number of well-established model organisms, we are aware of limitations to expand our interest, basic biological knowledge and evolutionary mechanisms of the polar-adapted species. We paid attention on the Antarctic copepods to develop the laboratory cultivation methods and more, to examine the potential as model species. Copepods, the small crustaceans are highly diverged with long evolutionary history and can survive temperatures below 0°C in polar regions and 45°C in hot springs. These abilities to survive under a wide range of environments are also advantageous in genetic comparative analysis for physical, chemical and biological studies. We have cultured the Antarctic new species Tigriopus kingsejongensis along with Tigriopus japonicus which were collected in west coast in Korea for comparative analysis. Here we report the first draft genome sequence and gene annotation for Antarctic Tigriopus kingsejongensis [1] and the comparison of those of T. japonicus, temperate species in same genus. Based on these results, we want Antarctic T. kinsejongensis to become established as a model species, expand our research interest and therefore accumulate a valuable informations of polar organisms.
