Caption: 3-D reconstruction of the internal organization of the tympanal organ in left tibia of a female Panacanthus pallicornis (Orthoptera: Tettigoniidae: Copiphorini). The animation highlights the morphological difference between the fluid-filled auditory vesicle and hemolymphatic channel. These two structures are clearly separated by a narrow joint. This video relates to a paper that appeared in the Nov. 16, 2012, issue of Science, published by AAAS. The paper, by Fernando Montealegre-Zapata at the University of Lincoln in Lincoln, UK, and colleagues was titled, "Convergent Evolution Between Insect and Mammalian Audition."
