They are herbivores feasting on fruits, nuts and nectars. Red ruffed lemurs have a life expectancy of about 15-20 years. They have acute hearing, eyesight, and smell along with 12 different complex calls to warn each other. Red Ruffed lemurs are considered critically endangered due to habitat destruction, hunting, and capture for pet trade.
