AUDITORY RESPONSES IN THE COMMON BOX TURTLE

Abstract
The auditory sensitivity of T. Carolina Carolina, was measured in terms of the inner-ear potentials. This ear resembles that of other species of turtles studied previously in that it shows keen sensitivity in the region of 100-600 cycles and progressively poor sensitivity for higher and lower tones. The tympanic membrane was found to undergo a rotational mode of movement in response to applied forces, swinging about a hinge formed by its posterior ligament.
