Many questions arise from these observations: Why do the sponges move? How do they orient themselves? Possible reasons for locomotion could be foraging, avoiding unfavourable environmental conditions, or to distribute offspring. 69 percent of our images showed trails of sponge spicules, many of which led to live animals,' reports Autun Purser. The seamount's summit was densely populated with sponges. 'With OFOBS we can create 3D models from the deep sea. The recently published recordings were made during an expedition at 87 °North at the Karasik Seamount about 350 kilometres away from the North Pole with the research icebreaker Polarstern in 2016 with a towed camera system OFOBS (Ocean Floor Observation and Bathymetry System). Antje Boetius, who works together with deep-sea biologist Dr Autun Purser from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in the HGF-MPG Joint Research Group for Deep-Sea Ecology and Technology. 'There are no strong currents in the Arctic deep sea that could explain the structures found on the sea floor,' explains expedition leader Prof. This is particularly exciting because science had previously assumed that most sponges are attached to the seafloor or are passively moved by ocean currents and, usually down slopes. 'We conclude from this that the sponges might actively move across the sea floor and leave these traces as a result of their movement,' reports Dr Teresa Morganti, sponge expert from the Max Planck Institute for Marine Microbiology in Bremen. These trails were observed to run in all directions, including uphill. The surprise was great when researchers looked at high-resolution images of the sea floor of the Arctic deep sea in detail: Path-like tracks across the sediments ended where sponges were located.
