Scientists finish first sea census


This physonect siphonophore (Marrus orthocanna) was photographed during NOAA’s "Hidden Ocean Expedition." The colonial animal is made up of many repeated units, which include tentacles, and multiple stomachs. Many specimens were observed at depths between 1,000 and 5,000 feet (300 to 1,500 meters).

This specimen of the jellyfish species known as Crossota norvegica was collected from the deep Arctic Canada Basin with a remotely operated vehicle.
