Bowhead whales have many unusual qualities. They can live for 200 years. They have the largest mouths of any living animal, yet only eat very small ocean creatures through a filter-feeding process. They have the thickest blubber, or fat covering, of any whale. Another interesting quality? Their underwater communication style has scientists comparing them to “jazz” artists. Researchers this week published findings of an intensive study of the vocalizations, or whale singing, of about 300 bowhead whales. The population they studied lived in waters east of Greenland. The researchers made the recordings from 2010 to 2014. They used an underwater microphone to gather the largest-ever collection of bowhead sounds. The recordings show many kinds of vocal sounds that changed often. The researchers identified 184 different songs within the population.
