Iriomote cat
In contrast to Imaizumi's assertions about its unique characteristics, other researchers strongly disputed the idea that the Iriomote cat is its own species ever since its discovery. Investigations involving skulls and teeth, samples and living animals, and genetic research were conducted. Because of these study results, it was subordinated under the genus "Prionailurus" as "Prionailurus iriomotensis" in 2005.
