Bushbabies, also known as galagos, are small primates, with long tails and large, hairless ears. Bushbabies possess big eyes that provide them powerful eyesight at night. Their ears are bat-like and allow them to track insects in the dark. They catch insects on the ground or snatch them out of the air. They are fast, agile creatures. As they bound through the thick bushes they fold their delicate ears back to protect them. They also fold them during rest. Galagos are nocturnal, with their most active times being during the crepuscular hours, and spend their nights foraging. Among the bushbabies, gestation lengths can range from around 111 days to around 142 with smaller species generally having shorter gestation lengths, and normally one young is born.
