Geochemists sampling the warm fluids issuing from rocks deep in the ocean have stumbled on an unusual sight: a nursery of dozens of octopus moms. The scientists were exploring a rocky outcrop 3 kilometers deep in the Pacific Ocean when they came upon an area full of Muusoctopus octopuses guarding their eggs, the U.S. National Science Foundation reports. Sadly, the creatures did not look well: Deep-sea octopuses live and breed in cold water, so the heat emanating from the rocks was not doing them or their eggs any good. But the researchers say that finding so many octopuses congregated together provides new insight into the breeding behavior of these creatures, which normally like to keep to themselves.
