Squid Video: Feeding on lanternfish in Sur Canyon
Watch the 'Sebastes' Phantom remotely operated vehicle (ROV) from NOAA Southwest Fisheries Science Center descend through the water column above Sur Canyon, CA. The robot meets a school of Dosidicus gigas near 370 meters depth. The Humboldt squid appear to be hunting bioluminescent Diaphus lanternfish in the water column. The squid follow the ROV down to the seafloor at 450 meters depth and strike the benthos, perhaps mistaking the lasers on the ROV for the bioluminescent fish.
The ROV is suspended from the NOAA ship Bell Shimada on a 500+ meter tether. The ROV is controlled by Dr. John Butler of NOAA SWFSC and his team of scientist-slash-ROV-pilots Scott Mau, Kevin Stierhoff, and Dave Murfin. Dr. Peter Etnoyer tagged along with support from Schmidt Research Vessel Institute. The team did a terrific job navigating 5 different sites in 3 different National Marine Sanctuaries along the West Coast last week.
