Echolocation has evolved in several mammals, including shrews. In bats, echolocation may occur through the larynx via the stylohyoid-tympanic articulation (ST-A). Using CT scans, we studied the morphology of the inner ear to determine if the ST-A is present in echolocating shrews. Of the nine sampled genera, three have behavioral data suggesting echolocation. Six species presented ST-A, including four species not known to echolocate. Given the limited behavioral data and the small data set, a few interpretations are possible, all of which highlight the need for additional research in this understudied mammalian group in order to reveal the role of the ST-A in shrew echolocation.
