WASHINGTON — Most octopuses lead solitary lives. So scientists were startled to find thousands of octopus huddled together, protecting their eggs at the bottom of the ocean off the central California coast.
The nesting site, which the scientists dubbed an "octopus garden," was first discovered in 2018 by researchers from the Monterey Bay National Marine Sanctuary and other institutions. The team used an underwater remote vehicle to film the throng of nearly 6,000 octopus nesting two miles deep. Only the hazy shimmer of escaping hot water meeting the frigid sea alerted the researchers to the hydrothermal seep. But they still didn't know exactly why the octopus had gathered there.
A male pearl octopus is seen at the "octopus garden," near the Davidson Seamount off the California coast at a depth of approximately 10,500 feet in an undated photo. Most octopuses lead solitary lives. So scientists were startled to find thousands of females huddled together, protecting their eggs at the bottom of the ocean. Research published Wednesday in Science Advance shows heat seeping up from the base of an extinct underwater volcano helps their eggs hatch faster.

Scientists solve mystery of why thousands of octopus migrate to deep-sea thermal springsResearchers used advanced technology to study a massive aggregation of deep-sea octopus gathered at thermal springs near an extinct underwater volcano off the coast of Central California. Warm water from hydrothermal springs accelerates development of octopus embryos, giving young octopus a better chance of survival. The Octopus Garden is the largest known aggregation of octopus on the planet -- the size of this nursery, and the abundance of other marine life that thrives in this rich community, highlight the need to understand and protect the hotspots of life on the deep seafloor from threats like climate change and seabed mining.
