Far beneath the Pacific Ocean, off the coast of Vancouver Island, a seemingly dormant underwater volcano has revealed a breathtaking secret—one that has left scientists both thrilled and puzzled. What began as a geological survey quickly turned into a remarkable biological discovery: a hidden nursery where thousands—possibly over a million—giant eggs are incubating in the warm embrace of volcanic heat.
This natural heat source has created a rare haven for marine life, especially deep-sea corals and sponges. But the true marvel came when the scientists spotted white skate rays (Bathyraja spinosissima) laying eggs in droves across the summit of the volcano—1.5 kms below the surface.
What stunned the team was the sheer scale of this reproductive gathering. Based on initial counts and image surveys, experts believe the site could be home to hundreds of thousands, possibly over a million eggs—a number that has never been documented for this species.
These rays produce egg cases nearly 50cm in length, resembling soft, curved pillows or even ravioli in shape. That’s massive by marine standards.
