Poulin, Elie The chemists shared the find with deep sea biologists, who were stunned. "comments": true, A hydrothermal vent is a fissure on the seafloor from which geothermally heated water discharges. The vents, where hot, mineral rich water warmed by magma flows deeper underground pours through cracks in the ocean floor, were only discovered in 1977. Researchers have been very concerned about the paucity of females of Vulcanoctopus hydrothermalis, an octopus inhabiting the hydrothermal vent … This is a unique community on Earth. Which begs the question: why would so many octopuses choose such a terrible spot to nurse their eggs? The warm water and low oxygen could have come later. Sea water enters, becomes very hot, and rises. Keep up-to-date on: © 2020 Smithsonian Magazine. The presence of the spires may uniquely enable this site to support simultaneous foraging by large numbers of octopuses. She is co-author of a study on the curious creatures that appeared this week in the journal.

A feeding frenzy of 12 octopuses of Vulcanoctopus hydrothermalis was observed from the manned submersible ‘Alvin’ at Parigo, a 2620 m deep hydrothermal vent on the East Pacific Rise. His work has appeared in Discover, Popular Science, Outside, Men’s Journal, and other magazines. Ocean water percolates through the cracks in the ocean crust and is heated at depth. There are hydrothermal vents along the Mid-Ocean Ridge and along some subduction zones.

Lai, Qiliang (In fact, researchers did note some tentacles waving from other, more inviting cracks in the rock.) 2010. A feeding frenzy of 12 octopuses of Vulcanoctopus hydrothermalis was observed from the manned submersible ‘Alvin’ at Parigo, a 2620 m deep hydrothermal vent on the East Pacific Rise. 2016. This data will be updated every 24 hours. While the researchers did not formally describe or name the new cephalopods, they did determine that they belonged to an undiscovered species in the genus Muuscoctopus. She is co-author of a study on the curious creatures that appeared this week in the journal Deep Sea Research Part I: Oceanographic Research Papers. Continue Xie, Yanrong According to the press release, much of the Dorado Outcrop may be an awesome place to raise an octopus family, with ideal spots for laying clutches in other cracks and fissures in the hardened lava. González, A.F. But Voight found that the developing octopus embryos couldn’t make it in the conditions near the volcanic vents the group had chosen. for this article. Not very much is known about these creatures but it is assumed that their eyes serve little or no purpose.

But, as Mindy Weisberger at LiveScience reports, they were stunned by the images that came back from two miles below the waves: hundreds of beautiful purple octopus mamas huddled around the vents, incubating their eggs. Deep-sea hydrothermal vent ecosystems are based on deep-dark energy derived from the oxidation of reduced compounds, leading to primary production by chemolithoautotrophs. 27 June 2005. "clr": false, However, animals at hydrothermal vents have special biochemical adaptations that protect them from hydrogen sulfide. and Although members of the prey species, Halice hesmonectes, are individually small (<5 mm long), the density of their swarms may make them attractive prey for the octopus.
