These bats usually press the fruit against the roof of the mouth to extract the juice and then spit out the remains, which can be found under popular feeding trees. Churned-up earth is an indicator of favourite feeding sites of feral pigs in the rainforest. These animals are potentially dangerous, so be careful. Eyeshine Many nocturnal animals have eyes that are adapted to low light conditions. Because of this, they are easier to find with a spotlight at night.
Light passes through the retina when it enters our eyes.
Some of this light is absorbed, and some of it is lost in the background tissues. Many nocturnal animals have what is known as a tapetum, which is a mirror-like membrane situated behind the retina, which reflects the light back through the retina again. The light that we see reflected in our spotlights is the remainder of this light that passes out through the eye again. Different animals produce a different brightness and colour of eyeshine. Humans, as seen in flash photographs, have a dull red eyeshine.
