For the first time, scientists have captured drone footage of sperm whales engaging in head-on collisions. The behavior was recorded during research fieldwork in the Azores and Balearic Islands between 2020 and 2022.
According to a study published in the journal 'iScience' in 2024, the whales were observed using their large heads to gently bump into each other. Researchers from the University of Southern Denmark and other institutions analyzed the footage, suggesting these interactions are a form of social communication rather than aggression.
The study notes that sperm whales have the largest brain of any animal and live in complex social groups. The observed headbutting appears to be a gentle, ritualized behavior, possibly used for greeting or bonding within their pods.
This discovery provides new insights into the social lives of these deep-diving whales, which are classified as vulnerable by the IUCN. The use of drone technology allowed for non-invasive observation of their natural behaviors at the ocean's surface.
