Discussion of the reptilian ear

Abstract

Evidence presented at this symposium lends support to the concept that the reptilian auditory apparatus shows major modifications which correlate with large taxonomic groups, and that lesser anatomical differences suggestive of adaptive change can be seen at subfamilial levels. Structures concerned with transmission, reception, and dampening of sonic vibratory energy are most frequently involved in modifications noted; thus, anatomical differences may account for diverse results of acoustic testing in reptiles. Preliminary investigation of the histology and cytology of certain features of the reptilian cochlear duct indicates considerable specialization at the cellular level and the need for continuing anatomical and physiological study. © 1966 by the American Society of Zoologists.
