November 16, 2020: Sea Star

This sea star was seen during a dive to explore the never-previously-surveyed Castellano Seamount at a depth of approximately 2,000 meters (6,562 feet) as part of the 2016 Hohonu Moana: Exploring Deep Waters off Hawaiʻi expedition. In this image, you can clearly see the tube feet on the underside of the sea star. Sea stars use these tube feet to move and also to hold prey.
