Groundbreaking Footage Reveals Sperm Whales' Remarkable Birthing Behavior

A team of researchers, led by a Canadian whale biologist, has made a significant discovery about the social behavior of sperm whales during childbirth.

The extraordinary video, captured in 2023, provides a unique glimpse into the lives of these elusive creatures and showcases their remarkable cooperation during a critical moment.

The footage shows female whales from two different family groups working together to assist a newborn calf, demonstrating a level of coordination rarely seen in the animal kingdom.

This level of cooperation is particularly noteworthy, as it is not commonly observed in animals, with the exception of primates like monkeys and humans.

There have been very few documented cases of sperm whale births over the past six decades, and most of these accounts are anecdotal or based on observations from whaling boats.

In a recent study published in the journal Science, researchers analyzed the rare footage and found evidence of cooperation among both related and unrelated sperm whales to support newborns.

Using drone footage, the researchers were able to capture the birth of a baby sperm whale and gain valuable insights into the behavior of these animals.

On July 8, 2023, a team of researchers was studying whale communication off the coast of Dominica when they stumbled upon an unusual gathering of whales.

Eleven whales, mostly females, were seen surfacing with their heads facing each other, thrashing and diving in and out of the water.

The researchers quickly deployed drones and microphones to capture the event, which lasted approximately 30 minutes.

For several hours after the birth, pairs of whales took turns holding the newborn calf above the water until it was strong enough to swim on its own.

One of the study's co-authors, David Gruber, described the event as a 'special moment' that provided a unique insight into the social behavior of sperm whales.

The researchers used drone footage to analyze the behavior of the whales and identify the social bonds that existed among them.

What was striking was the number of mothers, sisters, and daughters that came together to support the new calf, including some that were not related.

Sperm whales live in close-knit, female-led groups, and the observations suggest that these social bonds extend to the most vulnerable moments in their lives.

The discovery has left researchers in awe, with one of the study's co-authors, Shane Gero, describing it as 'amazing' to see these animals come together to succeed in the face of adversity.

Gero, a whale biologist and scientist at Carleton University, shared his experience with CBC Radio's Quirks and Quarks, describing the moment as 'surreal'.

Gero and his team had been observing the whales for about an hour when they noticed a large group of females, including grandmothers, mothers, and daughters, gathered together.

Initially, the researchers thought the whales were being quiet and defensive due to the presence of pilot whales, which are known to harass sperm whales.

However, about an hour later, a large amount of blood was seen in the water, and the researchers soon realized that a birth was taking place.

Gero described the moment when they saw the 'beautiful, tiny, little floppy flukes of the new baby' in the water.

The researchers then watched as the calf's mother and other whales, including its grandmother and 'aunties', lifted it out of the water on their noses.

At first, Gero thought the calf might be stillborn due to its floppy movements, but it soon became clear that it was alive and breathing on its own.

The researchers also noticed that the whales made different sounds during key moments of the birth, including slower, longer sets of clicks.

These findings were detailed in a separate report published in the journal Scientific Reports.

According to Gero, sperm whales communicate with each other using patterns of clicks, similar to a Morse code system.

The clicks and pauses changed during the birth, with the whales going from being relatively quiet to all communicating at the same time.

The noises may have played a role in aiding communication and helping the animals synchronize their efforts during the birthing process.

Gero also suggested that the whales may have been celebrating the birth, similar to how humans do.

The discovery has raised many questions, including how the group of whales formed and how they knew to join in.

Answers to these questions may take time, given the rarity of such video footage.

However, the new findings provide a glimpse into the hidden conversations of sperm whales and their social lives.

Biologist Susan Parks, who was not involved in the study, expressed excitement about the discovery, saying it is 'exciting to think about the social lives of these animals'.

The researchers on board the CETI vessel watched with joy as the newborn sperm whale was welcomed into the world.
