The mouse lemur is a small primate native to the island of Madagascar. It belongs to the family Cheirogaleidae and is known for its tiny size, with some species weighing as little as 30 grams. Mouse lemurs are nocturnal, meaning they are active at night, and they have large eyes that help them see in low light conditions. These primates primarily feed on insects, fruits, and nectar. Mouse lemurs are social animals, often living in small groups. They are also known for their agility and ability to leap between trees, making them well-adapted to their forest habitats.
