Eyes of the deep-sea floor: The integrative taxonomy of the Foraminiferal Genus Vanhoeffenella
Vanhoeffenella is a common deep-sea monothalamous foraminifer, some species of which have a unique eye-like test morphology. Owing to its world-wide distribution, it has been recorded numerous times since the “heroic age” of the deep-sea exploration in the early 20th century. So far, only 4 species...
