The scene was not just a touching snapshot captured by researchers in Western Australia, but a behavior that has long fascinated marine biologists. A female dolphin was observed continuing to carry her dead calf for days, refusing to let go, in a scene that reignited the scientific debate about how to interpret this behavior, and whether it reflects a form of emotional attachment, or an extension of the maternal instinct.
Field observation in Western Australia
Researchers from the non-profit Geographe Marine Research organization documented this behavior in the Leschenault Estuary in Western Australia, where a female dolphin, known to the research team as "Fraggle," was seen repeatedly pushing her dead calf to the surface of the water and continuing to move it around for days.
The Australian researchers explained that the female had previously lost young on several occasions, and that this time she remained attached to the body of her young, in a scene that the team witnessed during their field monitoring of the dolphin pod in the area.
Scientifically documented behavior
This incident is not an exception in the world of cetaceans, as scientific studies have documented multiple cases among dolphins and whales in which mothers or members of the herd continue to accompany or carry a dead individual after its death.
Researchers call this pattern "epimelic behavior," and it refers to the continued attempts to care for or stay close to the deceased individual despite their death.
In the Mediterranean Sea, studies have recorded cases of dolphins surrounding the bodies of their young or members of the pod for hours and days, while similar behaviors have been observed in different types of whales in other parts of the world.
Why carry it to the surface of the water?
In its first few weeks, a baby dolphin depends on its mother to help it reach the surface of the water to breathe, so many mothers are seen repeatedly pushing their dead baby upwards, as if they are still trying to help it breathe.
Researchers believe this behavior may continue for hours, and in some cases days, before the mother gradually abandons the body or it is swept away by ocean currents.
In February 2026, New Zealand’s Ministry of Conservation described this behavior as a documented natural phenomenon, after a female dolphin was spotted carrying her dead calf near a coastline, noting that this condition can last for days, and sometimes weeks.
What do scientists say?
The explanation for this behavior is still debated among researchers, but the most prominent hypotheses revolve around the continuation of the maternal care instinct after death, the strength of the bond between the mother and her young, or that the perception of death in dolphins may be a gradual process and not a single moment.
Science has not yet provided a definitive explanation, but the repeated observation of this behavior in different types of cetaceans and in far-flung regions of the world indicates that it is not a passing response, but rather a complex behavioral pattern that continues to reveal new aspects of the social life of these marine mammals.
Although researchers do not assert that dolphins experience grief in the human sense, such observations continue to expand scientists' understanding of their cognitive abilities and social bonds, and open the door to further studies to understand the relationship between instinct, social bonding, and cognition in the most complex of marine mammals.
