Scientists with Project CETI have captured rare video footage of a female sperm whale giving birth, revealing the cooperative behavior of the whales as they work together to protect the newborn calf. The footage provides a unique glimpse into the social dynamics and parenting strategies of these large, elusive marine mammals.

Why it matters

Sperm whales are a vulnerable species, and little is known about their birthing and early calf-rearing behaviors due to the difficulty of observing them in the wild. This new footage offers valuable insights that can inform conservation efforts and our overall understanding of sperm whale biology and ecology.

The details

The video, captured by Project CETI researchers, shows a female sperm whale giving birth as other adult whales in her pod gather around her, seemingly to shield and protect the newborn calf. The whales can be seen using their bodies to create a barrier, preventing the calf from drifting away or being exposed to potential threats during the vulnerable birthing process.

  • The footage was captured on March 29, 2026 by researchers with Project CETI.
