The Yakushima sika deer is a subspecies of sika deer found exclusively on Yakushima, a UNESCO World Heritage site in Japan. These deer are known for their distinctive spotted coats, which help them blend into the forest environment. They are medium-sized, with males typically larger than females, and they have antlers that grow annually. These deer primarily inhabit the lush forests of Yakushima, where they feed on a variety of vegetation, including leaves, fruits, and grasses. The population of Yakushima sika deer is considered stable, but they face threats from habitat loss and human activities. Conservation efforts are in place to protect their natural habitat.
