Scientists track sperm whales based on dialects
When the subjects of scientist Hal Whitehead’s research expeditions, sperm whales, returned to the Galapagos Islands after a 10-year absence he quickly assembled a new team to study the old whales. However, once the team began listening to the whale vocalizations, they discovered these were not the old whales they’d previously studied. They discovered this through the whales’ dialects.
