Wrinkle-lipped bat (Chaerephon plicata). This bat is found in South-East Asia. It roosts in huge numbers in caves. Photographed in Deer Cave, Borneo, the world's largest natural rock chamber. At the base of the cave, bat droppings collect in huge amounts and provide a food source to sustain an ecosystem of cave dwelling animals, known as troglobites.
