Image of the Day caption:
MIT/WHOI graduate student Ari Shapiro takes a break from listening to the vocalizations of narwhals. His computer screen shows a spectrogram--a plot of sound frequency versus time--of one of the whale's signals. Shapiro and colleagues found evidence that narwhals produce certain vocal signatures to help them recognize and reunite with family members nearby and at a distance.
