A bottlenose dolphin named Fraggle was filmed carrying its dead calf through the Indian Ocean off the coast of Western Australia [1, 2].
The footage provides a rare glimpse into the emotional lives of marine mammals. Observers and researchers said this specific behavior is an indication of grief and mourning within the species [1].
Fraggle was observed pushing the deceased calf on her head through the water [1, 2]. According to reports, the mother dolphin continued this behavior for over six days [1]. The calf was reportedly two weeks old at the time of its death [2].
The incident occurred in late March 2024 [1]. While the footage has gained significant attention online, it highlights the complex social bonds that exist between dolphins and their offspring. The act of refusing to let go of a dead calf is not a common occurrence, but it aligns with other documented instances of high-intelligence animals exhibiting mourning rituals.
Some reports on the event have varied regarding the location and duration of the behavior. However, data from the Indian Ocean region indicates the dolphin maintained the calf for nearly a week [1]. The physical effort required to keep a calf afloat is substantial, further suggesting a strong emotional drive behind the mother's actions [1, 2].
“The mother dolphin carried its deceased calf on its head for several days.”
This observation supports the growing scientific consensus that cetaceans possess the cognitive and emotional capacity for grief. By documenting the duration and physical effort of the mother's behavior, researchers can better understand the social structures and emotional intelligence of bottlenose dolphins in the wild.
