Abstract

Underwater Sensing Seals can detect prey up to 180 m away using their flow-sensing whiskers, which feature undulating morphologies that reduce vortex-induced vibrations. In article number 2207274, Ajay Giri Prakash Kottapalli, Xingwen Zheng, and co-workers investigate harbor and grey seal whiskers' interactions with the flow and find that neighboring whiskers in an array influenced one another by resulting increased vibrations compared to an isolated whisker, indicating a signal-strengthening effect in whisker arrays.
