Shapeshifting Deepstaria Jelly
During these first ever ROV dives in Revillagigedo Archipelago, the Nautilus team has encountered some truly otherworldly organisms. This Deepstaria jelly awed us with its shapeshifting abilities as its bag-like bell inflated and undulated with current created by movement of ROV Hercules. Capturing prey in its voluminous bell, a strikingly geometric network of canals delivers nutrients throughout this large jelly’s body.
This close encounter was captured with both our normal ROV Hercules HD camera and a low light camera for bioluminescence designed by Dr. Brennan Phillips at University of Rhode Island's Graduate School of Oceanography and David Gruber at the City College of New York/Baruch College.
Again moving offshore from the Baja California Peninsula, Nautilus will return for deeper exploration of the Revillagigedo Archipelago, consisting of the islands of Socorro, Clarion, San Benedicto, Roca Partida and numerous associated seamounts. Oceanic seamounts are critical features of the ocean basins that focus biological activity by providing hard substrates coupled with upwelling currents, are potential sites of seafloor mineralization, and pose hazards to benthic communities and human populations as a result of active volcanism.
