So he and his team suggest that lobtail feeding came about when humpbacks switched from hunting herring to catching sand lances, a type of fish.To track the spread of lobtail feeding in the whale population, the researchers combined data on fisheries stocks with a sampling of a long-term dataset (1980-2007) on humpback whale observations. .

Of these, 21 call types were the same as units of the song current at the time of recording but used individually instead of as part of the song sequence, while the other 13 calls were stable over the three years of the study and were not part of the song.

"That's not culture. Anthropogenic ocean noise has been increasing due to activities like sonar testing and vessel traffic from commercial and recreational use.Studies show that such noises can change humpback whale behavior.
