The Kerama deer (also Kerama Sika) is an endangered subspecies of the Sika deer native to the Kerama Islands.[1]
Kerama deer were imported from the Kagoshima Prefecture in the early 17th century. They were heavily hunted because they destroyed crops, causing the population to rapidly decline, and are now a government-protected species. The total known population was 130 as of 1995.[2] They have been designated a Natural Monument of Japan.[3]
Kerama deer have dark brown hair. Only the bucks have antlers, which are shed from March to April. They are small, weighing only about 75 kilograms.[4]
