@nautiluslive: You may not know it, but this deep-sea #isopod is a rare sight! Scientists still have much to learn about the long-limbed crustacean #Bathyopsurus, as only a few specimens (of only two species) have been collected. Join our team marveling as this segmented sea creature uses its large paddle-legs to power backward up into the water column. Our Corps of Exploration spotted this individual with ROV Little Hercules diving over 5,100 meters (16,700 feet) deep on the abyssal plain in Cook Island waters, making this a new record for the region. Sightings like this remind us of how much work it takes to observe #deepseaanimals in their natural habitat and how much we still have to learn about them
