    Description / Table of Contents: "The deep ocean comprises more than 90 percent of our planet's biosphere and is home to some of the world's most dazzling creatures, which thrive amid extreme pressures, scarce food supplies, and frigid temperatures. Living things down here behave in remarkable and surprising ways, and cutting-edge technologies are shedding new light on these critically important ecosystems. This beautifully illustrated book leads you down into the canyons, trenches, and cold seeps of the watery abyss, presenting the deep ocean and its inhabitants as you have never seen them before"--

    Notes: [Auszug] The deep ocean is home to a group of broad-collared hemichordates—the so-called ‘lophenteropneusts’—that have been photographed gliding on the sea floor but have not previously been collected. It has been claimed that these worms have collar tentacles and blend ...

    In:  Supplement to: Purser, Autun; Marcon, Yann; Hoving, Henk-Jan T; Vecchione, Michael; Piatkowski, Uwe; Eason, Deborah; Bluhm, Hartmut; Boetius, Antje (2016): Association of deep-sea incirrate octopods with manganese crusts and nodule fields in the Pacific Ocean. Current Biology, 26(24), R1268-R1269, https://doi.org/10.1016/j.cub.2016.10.052

    Description: Incirrate octopods (those without fins) are among the larger megafauna inhabiting the benthic environments of all oceans, commonly in water depths down to about 3,000 m. They are known to protect and brood their eggs until the juveniles hatch, but to date there is little published information on octopod deep-sea life cycles and distribution. For this study, three manganese-crust and nodule-abundant regions of the deep Pacific were examined by remote operated-vehicle and towed camera surveys carried out between 2011 and 2016. Here, we report that the depth range of incirrate octopods can now be extended to at least 4,290 m. Octopods (twenty-nine individuals from two distinct species) were observed on the deep Ka'ena and Necker Ridges of the Hawaiian Archipelago, and in a nodule-abundant region of the Peru Basin. Two octopods were observed to be brooding clutches of eggs that were laid on stalks of dead sponges attached to nodules at depths exceeding 4,000 m. This is the first time such a specific mineral-biota association has been observed for incirrate octopods. Both broods consisted of approximately 30 large (2.0-2.7 cm) eggs. Given the low annual water temperature of 1.5°C, it is likely that egg development, and hence brooding, takes years [Robison et al. (2014), doi:10.1371/journal.pone.0103437]. Stalked-sponge fauna in the Peru Basin require the presence of manganese nodules as a substrate, and near total collapse of such sponge populations was observed following the experimental removal of nodules within the DISCOL (DISturbance and COLonisation) area of the Peru Basin [Bluhm (2001), doi:10.1016/S0967-0645(01)00070-4]. Stalked fauna are also abundant on the hard substrates of the Hawaiian archipelago. The brooding behavior of the octopods we observed suggests that, like the sponges, they may also be susceptible to habitat loss following the removal of nodule fields and crusts by commercial exploitation.

    Description: Leg SO242/2 of an RV SONNE expedition to the DISturbance and reCOLonization (DISCOL) area in the manganese nodule ecosystem area of the Peruvian Basin in the framework of JPI Oceans program ‘Ecological aspects of deep-sea mining’ and MIDAS investigated the faunal and biogeochemical response and recovery to both recent (~5 weeks prior) and historical (~26 yrs prior) nodule removal and seafloor disturbances. Recently published by MIDAS partners, epifauna studies conducted within the Clarion Clipperton Fracture Zone (CCZ) as part of the same projects have shown the potential importance of manganese nodules as suitable hard substrate ‘islands’ onto which stalked fauna, such as deep sea sponges and crinoids, can settle and develop (Vanreusel et al., 2016). At the DISCOL site, 27 deep sea incirrate octopi were observed actively feeding around the edges of Manganese nodules at depths of approx. 4100 m, using crevices between nodules as sites of refuge, and in two instances brooding eggs directly onto the stalks of dead deep sea fauna. Interestingly, no incirrate octopi were observed during any of the recent MIDAS / JPI Oceans cruises to the CCZ, Observed individuals represent at least two species, with several being identified as Vulcanoctopus sp. The majority appear to belong to the recently observed ‘Casper’ species, recorded by Remote Operated Vehicles from several locations within the Hawaiian archipelago, and as yet, undescribed. Together with the recent Hawaiian observations, these new data increase the depth range of incirrate octopi by several hundreds of meters. Additionally they represent the first observations of incirrate octopi using other fauna as a brooding substrate. Though the knock-on impacts on stalk supported small megafauna communities has been a known consideration for several decades (though better understood following MIDAS and JPI Oceans investigations) the potential impacts on larger semi-pelagic mobile fauna such as octopi has not been considered to date. In this study we show that potentially the loss of nodules will have direct impacts on these larger megafauna. Tantalisingly, the observations of the incirrate octopi in the Hawaiian archipelago were made in areas also abundant in stalked fauna. Survey dives within these manganese crust rich regions of seafloor covered considerably less area than the DISCOL work carried out during SO242/2, and therefore there is the potentiality that stalks in these commercially interesting ecosystems represent habitat resources at risk from mining activities.
