Dive 6: Deepwater Siphonophore

On March 14, during the sixth dive of the expedition, this intact deepwater siphonophore was observed. Although they may appear to be a single organism, these giant siphonophores are actually comprised of a colony of individual hydrozoans, each specialized for different functions such as swimming, feeding, and reproduction.
