DNA and underwater footage reveal two new species of deep-sea siphonophores

New research is shedding light on the diversity of deep-sea siphonophores. A team of scientists from MBARI, the University of Gdańsk, New York University and Yale University conducted a comprehensive examination of Bargmannia siphonophores using museum material, submersible observations and genomic sequencing. This work uncovered two previously unknown species: Bargmannia marlena and Bargmannia pyrosa. The team published their findings in the Zoological Journal of the Linnean Society last week.
