What Does Dinner Sound Like?

October 21, 2010

Squid such as this Loligo pealii are a major prey item of many fish, whales, and human fishermen. WHOI researchers are using acoustics to study how whales use sonar to find squid, how humans might do the same, and whether squid can detect hunting whales and take evasive action. Wu-Jung Lee, a graduate student in the MIT/WHOI Joint Program, is elucidating what the sonar echoes from squid sound like to whales and human sonar systems. Aran Mooney, a post-doctoral scholar, is trying to determine whether squid can detect the bio-sonar signals from whales that are hunting them.
