Mother whale grieves stillborn calf

Off Australia's Gold Coast, a humpback whale mother stayed with her dead calf for hours or days, maintaining eye contact and positioning herself close by. An escort whale accompanied her throughout.

“She remained close to the calf, maintaining eye contact and positioning herself next to her calf over several hours and maybe even days.”

Researchers document maternal grief

Griffith University researchers led by Dr. Olaf Meynecke analyzed the footage and concluded the mother's behaviors matched care-giving and post-mortem responses seen in socially complex mammals.

“These observed behaviours were consistent with care, giving or nurturing actions and post, mortem attentive responses documented in socially complex mammals.”

First time in baleen whales

While toothed whales and dolphins have shown attentive behavior after deaths, this is the first documented case in a baleen whale species like humpbacks.

Witness describes unusual behavior

Sea World Foundation rescue boat captain Andrew Mulville first thought he was seeing two whales resting, but realized their behavior was distinctly unusual and unexpected.

“At first sight, I thought it was just two whales resting on the surface, but their behaviour was unusual.”

Grief reveals emotional complexity

The observation suggests humpback whales have cognitive and emotional capacities that allow them to process death and form strong social bonds, similar to humans.

“Understanding how non-human animals responded to death provides insight into their emotional lives, social bonds, and cognitive capacities.”

Need for more documentation

Researchers say continued systematic documentation of rare neonatal mortality events in large whales is essential to better understand the evolutionary and emotional significance of post-mortem behavior.

Cats also show signs of mourning

Recent research from Oakland University surveyed 412 cat owners and found surviving cats showed grief indicators including changes in sleeping, eating, playing, and attention-seeking after a companion's death.

Grief intensity depends on bond

The Oakland University study found that cats who lived longer with deceased companions showed stronger attention-seeking behaviors afterward, suggesting grief intensity correlates with relationship duration.

“The longer the cat had lived with the deceased animal, the more the caregivers reported increases in attention-seeking following the death.”

Humpbacks migrate vast distances

Humpback whales travel up to five thousand miles annually between tropical breeding grounds and colder feeding areas, making them one of the longest-migrating mammals on Earth.

Population recovery from whaling

Some humpback populations, particularly off eastern and western Australia, now number over twenty thousand animals. These same populations were nearly eradicated by whaling sixty years ago.

Arabian Sea population critically small

The smallest known humpback population inhabits the Arabian Sea year-round and may number as few as eighty individuals, making it extremely vulnerable to extinction.

Entanglement threatens whale survival

Humpback whales become entangled in fishing gear, moorings, and nets, often dragging equipment for long distances. This causes fatigue, feeding problems, and severe injury. Most whales experience entanglement at least once in their lives.

Multiple threats to whale populations

Humpbacks face declining food supplies from climate change and industrial fishing, vessel strikes in busy shipping lanes, and underwater noise that disrupts communication and increases stress hormones.
