Lemurs are primates native to the island of Madagascar. They come in a wide variety of sizes and colors, ranging from the tiny mouse lemur, which weighs just 30 grams, to the larger indri, which can weigh up to 9 kilograms. Lemurs are known for their unique adaptations, including their long, furry tails and their ability to climb trees with ease. Sadly, many lemur species are threatened with extinction due to habitat loss and hunting.
