Through her analysis of sonar echoes from squid, WHOI/MIT Joint Program student Wu-Jung Lee found that the shape made by the squid's tentacles greatly influences how sound waves reflect off the squid. A squid with its tentacles folded (left) produces a very different echo than a squid with its tentacles open or splayed (right).
These photos show the squids Sepioteuthis sepioidea and Histioteuthis sp., which may or may not be eaten by dolphins or toothed whales. (Photos by (left) Roger Hanlon, Marine Biological Laboratory and (right) Larry Madin, Woods Hole Oceanographic Institution)[back]
