Rare sperm whale birth captured on camera reveals astonishing teamwork

Scientists have captured rare footage of a sperm whale giving birth in 2023. The event, documented in two new studies, offers an unprecedented look at how these marine mammals support each other during labour. Such recordings are extremely uncommon, with only a few anecdotal accounts from the last six decades. The birth unfolded over roughly 30 minutes, with female whales from two different family groups working together. They helped lift the newborn calf above the water for hours afterwards, ensuring it could breathe. This level of coordination is rarely seen outside primates.

The whales also produced distinct sounds at key moments, possibly to synchronise their actions. These vocalisations suggest a complex form of communication during the birth. Sperm whales live in tight-knit, female-led societies, and the footage confirms these bonds extend to childbirth. Researchers noted how the group's behaviour raised questions about their social structure and decision-making. Prior to this, most birth records came from whaling boats or unverified sightings. Video evidence of sperm whale births remains difficult to obtain, making this documentation particularly valuable. The findings were published in *Scientific Reports* and *Science*, highlighting the significance of the discovery.

The footage provides the first clear record of sperm whale birth behaviour in the wild. It reveals how these animals rely on teamwork and vocal cues to assist labour. Scientists now have new insights into their social dynamics and survival strategies.
