How can bushbabies often be given away during a nocturnal search in a park?
Answer
The reflection of their large eyes from a flashlight beam.
The physical adaptation of the bushbaby's eyes is key to spotting them in the pitch black of night. Their eyes are immensely large and perfectly suited for maximizing the collection of scant available light during nocturnal activity. Because of this specialized visual apparatus, when a searcher directs a flashlight beam toward them, their eyes strongly reflect the light, creating a distinctive visual signature often referred to as 'eye-shine.' This brief, telltale reflection is frequently the first indication that a bushbaby is present, especially as they often freeze momentarily when caught in the beam while active.
