Giant Siphonophore Sighting | Nautilus Live

During the 2015 ECOGIG dives in the Gulf of Mexico, the team spotted a giant siphonophore that seemed to stretch for several feet. E/V Nautilus is exploring the ocean studying biology, geology, archeology, and more. Watch for live video from the ocean floor. For live dive updates follow along on social media at and on Twitter.
