Several authors have noted the reduction and loss of TME structures (e.g.,16–20) or morphological variations in middle ear structure (e.g.,1,21–23) in bufonids, but the phylogenetic distribution of earlessness has never been stud- ied either within Bufonidae or across Anura. As such, ...
Most anurans possess a tympanic middle ear (TME) that transmits sound waves to the inner ear; however, numerous species lack some or all TME components. To understand the evolution of these structures, we undertook a comprehensive assessment of their occ
