Image of The Day caption:
Wu-Jung Lee, a graduate student in the MIT-WHOI Joint Program, adjusts the apparatus that allows her to record sonar echoes from a squid at different orientations. She is trying to determine how dolphins and toothed whales use sonar to distinguish squid, which they eat, from other animals that they do not eat. In her experiments, squid are suspended from a frame that rotates through a full circle one degree at a time, allowing her to direct sonar pings at the squid from 360 different angles. An underwater microphone receives the echoes that bounce off the squid and records them into a computer for acoustic analysis. An anesthetized squid (Loligo pealii) is in the plastic container just past her hands.
