Squid Scan

WHOI biologist Aran Mooney and Dr. Iliana Ruiz-Cooley, a postdoctoral scientist at the NOAA-National Marine Fisheries Service Southwest regional office, examined a Humboldt squid before scanning its sensory structures at the WHOI Computerized Scanning and Imaging Center. Mooney, who studies how animals use sound underwater, was the first to demonstrate that Atlantic long-finned squids (Loligo pealeii) respond to underwater sounds, indicating that they can hear. Next, he plans to test sound responses of living Humboldt, or “jumbo,” squids (Dosidicus gigas). (Photo by Tom Kleindinst, Woods Hole Oceanographic Institution)
