Two scientists, one from the University of Salamanca and the other from Yale, have discovered that the presence of predators affects behavior patterns of a species of lizzard called acanthodactylus beershebensis from the Negev Desert in the Near East. These lizzards move less and catch less mobile and different prey while under pressure from predators. These two scientists basically discovered that this particular species of lizzard can diet to avoid being eaten. The scientist from the University of Salamanca stated," The lizards' diet and food-seeking behaviour changed significantly when we experimentally increased the predation pressure on them"
