Heartbreaking Humpback Vigil Challenges Scientists

In a deeply poignant display, a mother humpback whale was filmed interacting with her stillborn calf off the Gold Coast of Australia, bringing attention to rarely observed post-mortem behaviour in these marine giants. This encounter, documented in July 2025, marks the first scientifically recorded instance of such behaviour in humpback whales. Video evidence shows the whale persistently returning to her calf’s lifeless body, touching it gently and positioning herself closely for prolonged periods, showcasing a level of maternal attention seldom seen.

Scientifically Noteworthy Observation

The study, published by Discover Animals, and covered by outlets such as ABC News and Griffith University, highlights the mother’s extended contact with the calf, a stark departure from typical behaviours observed in similar species. In particular, baleen whales like humpbacks are not often seen demonstrating such responses, likely due to the challenges of observing these events in vast ocean expanses.

Unique Behaviour Among Baleen Whales

While socially complex mammals such as dolphins and orcas have shown similar grief-like responses, humpback whales rarely provide such opportunities. The incident may be explained by the tendency of deceased calves to sink due to insufficient blubber, making post-mortem observations rare. The mother’s refusal to attempt uplifting the calf might suggest recognition of its unresponsiveness, though definitive conclusions about the emotional context remain elusive.

Understanding Whale Grief: A Complex Challenge

Researchers exercise caution in interpreting these behaviours, coining the term “post-mortem attentive behaviour” to describe the interaction. Theories about the whale’s actions range from maternal instincts to potential confusion or a sudden sense of loss. Further research and more documented cases are essential to draw conclusions about grief in humpbacks.

A Glimpse into Whale Maternal Bonds

This rare event not only touches on the emotional bonds between mother whales and their offspring but also opens a window into the potential complexities of whale behaviour. Continuous observations and studies of birth and death scenarios in marine mammals could unearth further evidence, shedding light on whether such deep responses are common.
