Nearly all studies of their acoustic communication focus on sound pressure measurements, overlooking the particle motion components of their communication signals. Humpback whale song can be detected over large distances. Less is know about how far their particle…

Auditory anatomy and uCT As a comparison to some of our physiological and behavioral measurements, we are examining auditory anatomy of some select study animals. With Song Zhongchang and James Michaelson, we are leveraging microCT imaging technology to reconstruct the ultrafine hearing structures of snapping shrimp, puffins, black sea bass, and squid. For some of…
