The object of this research is to compare zoology and botany name caused by language and science differences of South and North Korea since division. Biological data are collected North Korea bio- logical information (flora and fauna, an illustrated flora and fauna book of North Korea, Etc.) and com- pared both side data based on national species list of korea, National Institute of Biological Resources. We could built 3,903 species of flora and 1,487 species flora on biological database. The criteria for comparative method is 5 types (korean name difference, scientific name difference, same species, sim- ilar species, North Korea endemic species). As a results, plants were identified korean name difference (911 species), scientific name difference (614 species), same species (880 species), North Korea en- demic species (1,037 species) of 3,903 species, and animals were korean name difference (685 spe- cies), scientific name difference (104 species), same species (199 species), North Korea endemic spe- cies (226 species) of the 1,492 species. This results are expected to be in application with cooperation study for recovering bioinformatics differences of South and North Korea.
