Deep-Sea Discoveries — While exploring the submarine flanks of the newly recognized Ka‘ena Volcano (offshore O‘ahu, Hawai‘i) with the ROV Jason, our team of geologists had a scientific encounter of another kind. A deep-sea octopod we saw during one of the dives turns out to be a new species, previously unknown to science! Nicknamed "Casper," these charismatic creatures have since been observed on Necker Ridge further up the Hawaiian chain, and in the Peru Basin, where some were observed brooding eggs on stalked sponges. A new paper in Current Biology documents these observations and discusses the potential impacts of deep-sea mining on its habitat.
