First aired back in 2020, this episode follows the story of an octopus living one mile under the ocean as she performs a heroic act of heart and determination.

In 2007, Bruce Robison’s robot submarine stumbled across an octopus settling in to brood her eggs. It seemed like a small moment, but as he went back to visit her month after month, what began as a simple act of motherhood became a heroic feat that has never been equaled by any known species on Earth. 

This episode was reported and produced by Annie McEwen. 

Special thanks to Kim Fulton-Bennett and Rob Sherlock at the Monterey Bay Aquarium Research Institute.
