The sea pen Umbellula huxleyi Kölliker, 1880 was originally described based on specimens from Japan, as a result of the Challenger Expedition. In the years that followed, the species has also been reported from the Northeast Atlantic (Porcupine Seabight, NW Ireland). Through integrative taxonomy, including morphological examination, in situ imagery, and DNA sequences (mtMutS, COI, and 28S), we show that the species is also found in the Northwest Atlantic, specifically in Davis Strait, Canada, and Iceland. The species was found at a depth of 574 m during a remotely operated vehicle dive in Davis Strait and between 1267 and 1304 m in Iceland, falling within the known bathymetric range of the species, although the 574 m record is shallower than most records. We also compared our specimens to a lectotype from the UK’s Natural History Museum collection. U. huxleyi has a round axis and lacks sclerites in the rachis. There is only one other known species of Umbellula with these characteristics (Umbellula spicata Kükenthal, 1902), and we discuss their differences. We also provide the first in situ recording of bioluminescence in U. huxleyi.
