animal

This butterfly once lived in the mangrove forests along the tropical coast of Taiwan. But in the 1960s, as people built more homes and roads in these coastal habitats, the Juvia Large Crow lost its food and only habitat. This species eventually became extinct--it is gone forever. Today, the remaining coastal forests and mangroves are protected by law. But it's too late to save the Juvia Large Crow.
