The Tokunoshima spiny rat, Tokudaia tokunoshimensis, is a rodent found only on the island of Tokunoshima in the Satsunan Islands of Japan. Because its habitat is so small it is considered endangered. It is commonly found in the secondary and primary subtropical moist broadleaf forests of the island. Its karyotype has an odd diploid number, 2n = 45, and, like its relative Tokudaia osimensis, it is one of the few mammals that lack a Y chromosome and the SRY gene. The species is threatened by deforestation and by predation from feral cats and dogs.
