"Sound is one of the most important cues for marine animals. Light doesn't travel well through the ocean. Sound does much better," says Mooney, who is a Grass Fellow at the MBL and beginning postdoctoral research at Woods Hole Oceanographic Institution this fall. He predicts that squid probably hear very low-frequency sounds, which means they pick up on fish tones and boat traffic. A better understanding of what these animals hear could reveal how human-induced noise affects cephalopods and how their auditory system evolved separately from that of fish.
Sharing the Grass Lab with Mooney are two other fellows investigating animal behavior. Keram Pfeiffer of the University of Marburg in Germany is training bees to respond to polarized light and Gwyneth M. Card of Caltech is recording how flies decide to initiate flight. They are among nine people to receive 2008 fellowships from the Grass Foundation to conduct summer research in neurobiology at the MBL.
Lost an Appendage? Grow Another
Cut off one finger from a salamander and one will grow back. Cut off two and two will grow back. It sounds logical, but how the salamander always regenerates the right number of fingers is still a biological mystery.
The salamander isn't the only animal with this regenerative ability. Take the sea squirt, Ciona intestinalis, a cylindri
