Researchers discover the heat seeping up from an underwater volcano off the central California coast has halved the hatching time for pearl octopuses.
abc.net.au/news/research-shows-heat-helps-octopus-eggs-hatch-faster/102769812Small deep-sea octopuses are huddling around an extinct underwater volcano as a natural incubator to help their eggs hatch faster, researchers say after three years of observations.
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. "They were pushing away potential predators and turning over their eggs," for an even flow of water and oxygen, said marine biologist and co-author of the study Andrew DeVogelaere.
The researchers found that eggs at the site hatch after about 21 months — far shorter than the four years or more it takes for other known deep-sea octopus eggs.
