The Mexican characid Astyanax mexicanus gave rise to a series of cavernicolous populations ("Anoptichthys") not earlier than during the Pleistocene age. When searching for food the blind cave fish swims at an angle of about 45 degrees to the ground. The river fish, however, when having no visual information, stands vertically on its head. With the aid of infrared-videorecording and on the basis of crossing experiments it could be demonstrated that this difference in feeding behaviour is… CONTINUE READING
