Frenulate siboglinids at high Arctic methane seeps and insight into high latitude frenulate distribution
Abstract Frenulate species were identified from a high Arctic methane seep area on Vestnesa Ridge, western Svalbard margin (79°N, Fram Strait) based on mitochondrial cytochrome oxidase subunit I (mtCOI). Two species were found: Oligobrachia haakonmosbiensis , and a new, distinct, and undescribed Oli...
