Sperm Whales Assist During Birth Like Family Midwives

When whale biologist Shane Gero spotted a group of sperm whales floating quietly near Dominica's coast in July 2023, he knew something unusual was happening. These whales weren't sleeping or socializing—they were preparing for something remarkable.

Suddenly, the whales started diving and rolling as blood filled the water. Gero's first thought was an attack, but then a tiny head popped up: a brand new baby sperm whale being born right before his eyes.

What happened next stunned the research team. All 11 members of the whale group, called Unit A, took turns gently lifting the newborn to the surface with their bodies. The mother, Rounder, worked alongside her half-sister Aurora and a young female named Ariel to keep the baby afloat and safe.

The team scrambled to capture everything on camera and drone footage, even cooling overheating batteries in their boat's freezer. For the first time ever, scientists documented the entire birth process from start to finish.

Using machine learning to analyze the footage, Gero and his colleagues from Project CETI discovered the whales appeared to communicate and coordinate their movements. They worked like experienced midwives, each taking a role in supporting the struggling newborn.

Young sperm whale calves naturally sink and must work harder than adults to reach the surface for air. The group's careful positioning likely saved the calf's life in those critical first hours.

Why This Inspires

This behavior was previously thought to exist only in humans and our closest primate relatives like bonobos. Watching these ocean giants tenderly care for their newest family member reminds us that compassion and cooperation run deeper in nature than we ever imagined.

The whales may have also been protecting the vulnerable newborn from pilot whales spotted nearby earlier that day. Whatever their exact motivation, their instinct to help was immediate and unwavering.

Today, that baby whale still swims healthy and strong through Caribbean waters, raised by an entire community that welcomed it into the world together.
