Scientists have captured first-of-its-kind footage of a sperm whale violently headbutting another sperm whale out of the blue.
Researchers filmed the clip with a drone during fieldwork off the Azores and Balearic Islands. It is one of three cases of headbutting between 2020 and 2022 that the scientists reported in a new study published Monday (March 23) in the journal Marine Mammal Science.
