On March 14, while exploring on an unnamed seamount west of the Winslow Reef complex during the sixth dive of the Discovering the Deep: Exploring Remote Pacific Marine Protected Areas expedition, this intact deepwater siphonophore was observed. Although they may appear to be a single organism, these giant siphonophores are actually a colony of many individual hydrozoans, each specialized for different functions such as swimming, feeding, and reproduction.
