This 2022 image from video provided by MBARI shows a time-lapse camera used to monitor aggregations of female pearl octopuses (Muusoctopus robustus) nesting at the "octopus garden," near the Davidson Seamount off the California coast at a depth of approximately 3,200 meters (10,500 feet). Most octopuses lead solitary lives. So scientists were startled to find thousands of them huddled together, protecting their eggs at the bottom of the ocean. Research published Wednesday, Aug. 23, 2023, in Science Advance shows heat seeping up from the base of an extinct underwater volcano helps their eggs hatch faster. (MBARI via AP)
