Vision in echolocating bats works complementary to their echolocation signals and is especially important in long-range orientation. Contrary to previous predictions, we report here the first case of blindness and ocular anomalies in healthy adult echolocating bats. Two anomalous individuals of Carollia perspicillata, two Artibeus planirostris and one Artibeus lituratus were captured in highly human-modified areas (urban and agricultural). One C. perspicillata was totally blind exhibiting completely closed eyelids and the others presented strong corneal opacity in their right eye. Our finding brings new insights about the habitat perception in mammals and suggests an unreported ecological compensation of the sensory system in bats. [ABSTRACT FROM AUTHOR] |
