Mother humpback whale's vigil over stillborn calf documented for first time

Scientists monitoring waters off the Gold Coast witnessed an extended period of maternal attentiveness as a humpback whale remained close to her stillborn calf on the ocean floor. The observation, which continued for several hours, represents the first documented instance of such behaviour in humpback whales and provides significant evidence of the species' complex emotional and social responses to loss.

The incident underscores the profound maternal bonds that exist within humpback whale populations, challenging earlier assumptions about cetacean responses to offspring mortality. Researchers say the mother's sustained proximity to the deceased calf suggests emotional engagement beyond basic biological imperatives, potentially indicating grief or mourning responses similar to those documented in other intelligent marine mammals.

Scientists are now calling for expanded observational efforts to better understand post-mortem maternal behaviour across humpback populations. The findings could reshape current understanding of whale cognition and emotional capacity, with implications for marine conservation and animal welfare policies. Further research is expected to determine whether such behaviour is widespread among humpbacks or represents an isolated occurrence.
