Whales have accents and regional dialectsWhen they dive together, sperm whales make patterns of clicks to each other known as "codas". Recent findings suggest that, not only do different codas mean different things, but that whales can also tell which member of their community is speaking based on the sound properties of the codas. Just as we can tell our friends apart by the sounds of their voices and the way they pronounce their words, different sperm whales make the same pattern of clicks,...

Scientists are now saying that marine mammals are not only smarter than previously thought, but many also share several attributes once claimed to be exclusively human. Cetaceans, an order of more than 80 whales, dolphins and porpoises, have the ability to express self-awareness, suffering and have social cultures with high mental abilities, say marine biologists. If the notion is true that whales are intelligent and sentient beings, it would threaten to destroy the assumption that they are...

A new study suggests that sperm whales may team up and work cooperatively to hunt down and corral their food. Scientists from the U.S. used high-tech GPS tags to study the marine mammals' astonishing hunting behaviors. The tracking equipment showed how the animals traveled together in groups, but when it came time to hunt for food, each whale took on various roles within the group. The study, led by Professor Bruce Mate from the Hatfield Marine Science Center in Oregon, used new equipment...
