Humpback Whale Filmed "Grieving" Her Dead Calf — Scientists Say It's a World First

A quiet stretch of ocean off Australia's Gold Coast has produced one of the most emotional pieces of wildlife footage in years — and it's the reason "humpback whale" is trending across the world right now.

Marine researchers have released rare drone footage showing a female humpback whale staying close to her stillborn calf on the seafloor, touching it gently with her head and fin, for hours after giving birth. Scientists say it's the first time this kind of behavior has ever been documented in humpback whales, and it's raising fresh questions about whether these giant ocean mammals experience something close to grief.

What Actually Happened

The footage was captured in July 2025 in the waters off Palm Beach, near Queensland's Gold Coast, but the research describing it was only made public this week. In the video, a mother humpback repeatedly returns to her calf's body, lying motionless beside it while keeping eye contact and making physical contact with her fin and head. A second adult whale, believed to be a companion or "escort," stayed nearby the entire time.

Sea World Foundation rescue boat captain Andrew Mulville was the first to notice something unusual. He initially assumed the two whales were simply resting near the surface, until their behavior made it clear something far more significant was unfolding. According to researchers, the mother stayed with her calf for at least a couple of hours, and possibly much longer — some reports suggest she may have remained nearby for days.

Why Scientists Are Calling This a Big Deal

Marine ecologist Dr. Olaf Meynecke of Griffith University's Whales and Climate Research Program led the study, which was published in the journal Discover Animals. He explained that this kind of post-mortem attentiveness — where a mother lingers with, touches, or protects a dead offspring — has been seen before in toothed whales and dolphins, such as orcas. But it had never been formally documented in baleen whales like humpbacks, which make up a completely different branch of the whale family tree.

What makes this case unusual, researchers say, is that the whale did not try to push the calf to the surface, a behavior that's sometimes reported in other whale species. That detail hints she may have recognized the calf was already gone shortly after birth. Instead, she stayed beneath the surface with the body, engaging in behavior the researchers describe as consistent with caregiving, nurturing, and a strong maternal bond.

Scientists are careful with their wording here. They stop short of confirming this is grief in the human emotional sense, since that's extremely difficult to prove in a wild animal. But they do say the behavior lines up with what's been observed in other highly social, intelligent mammals — elephants, primates, and orcas among them — when responding to the death of an offspring or companion.

It's worth noting this isn't the first time a mother whale's response to a dead calf has captured public attention. In 2018, an orca known as J35 made global headlines after she was seen carrying her dead calf on her back for more than two weeks along the coast of Washington State, a moment researchers at the time called an unprecedented display of grief. The new humpback footage adds a rare data point from an entirely different whale species.
