Exclusive: Deep-Sea Sharks and More Spotted by New Camera

April 21, 2015 - National Geographic's remote imaging team uses drop-cam technology to explore deep ocean mysteries. In this video, mechanical engineer Alan Turchik explains how the drop cam works and reveals footage of underwater life never before seen in the Chagos Archipelago in the Indian Ocean. The camera captured images of a gulper shark, not previously known to occupy these waters. The January 2015 expedition was organized by the Bertarelli Foundation and led by Zoological Society of London researcher Tom Letessier. The National Geographic Society/Waitt Grants Program also supported the expedition.
