The blue-eyed black lemur (Eulemur flavifrons) was recently born as part of the conservation program at Jacksonville Zoo and Gardens. Blue-eyed black lemurs are some of the most threatened primates in the world. The lemurs are classified as critically endangered on the International Union for Conservation of Nature (IUCN) Red List of at-risk species. Blue-eyed black lemurs have been named among the 25 most threatened primates on Earth. Their population numbers have dropped 80% over the past three generations or 24 years. Scientists estimate that there will be an 88% reduction in the lemurs' range from 2000 to 2080 due to climate change alone. Blue-eyed black lemurs are sexually dichromatic, meaning that males and females have very different appearances. Males are totally black while females are reddish-brown to grayish-orange. When they’re born, babies have brown fur that blends in with their mother. As they get older, the fur on male lemurs will eventually turn black. They are the only primates, other than humans, that can consistently have blue eyes. Blue eyes are uncommon in the wild because they offer less protection from the sun than eyes with darker irises. They weigh about 5 pounds (2.4 kilograms) and are about 38 inches (1 meter) long. They have long, bushy tails that they will often keep high in the air as they move around. About the Lemur Baby Jacksonville Zoo and Gardens The lemur pup is the second successful birth of a blue-eyed black lemur at the zoo. The baby was born to mom Hendricks and dad Hemsworth, a pair that came to the zoo in 2017. Their first pup was a girl who left to go live at the San Diego Zoo in July 2021. Keepers don’t know the new baby’s gender yet. They are giving the family quiet time and space in these early days of development. “We have many reasons to celebrate this new infant. He or she will further enrich the social environment and experience of the Zoo’s amazing mixed-species lemur group and strengthen the sustainability of the Blue-eyed black lemur population,” Tracy Fenn, assistant curator of mammals, said in a statement. “The Madagascar team is elated to see this infant thriving in the care of the mother.” Threats and Habitat Loss The main threat to the blue-eyed black lemur’s survival is habitat loss. The species is found in a very limited area of northwestern Madagascar. The island country lost 37% of its forest from 1973 to 2014, according to the IUCN. Almost half of Madagascar’s remaining forest is located within 328 feet (100 meters) from the edge of the forest. Habitat is lost as more forest is converted into agricultural land. Logging, mining, and forest fires have also destroyed much of the lemurs’ home. In some cases, the animals are also hunted for food or trapped to keep as pets.
