When Lady Gaga releases a new single, it quickly goes around the world.
Now scientists have discovered the same thing happens with the songs of another unusual and interesting creature – the humpback whale.
The mammals become interested in new tunes just like people do, and the most popular original whale songs spread globally like hit singles.
The discovery has astonished experts who say it is the first time such a large, “population-wide cultural exchange” has been seen in the animal kingdom.
Male humpback whales are well-known for the loud, long and complex songs they make during the mating season. Scientists are unsure why the males sing. Some believe it is a way of advertising themselves to females, others that it allows migrating(迁徙)whales to stay in contact.
Each song lasts for 10 to 20 minutes
