New and poorly known benthic foraminifera (Protista, Rhizaria) inhabiting the shells of planktonic foraminifera on the bathyal Mid-Atlantic Ridge
Based on sediment samples from the Mid-Atlantic Ridge (MAR; 49–54°N, 2508–2772 m water depth) we redescribe Hospitella fulva Rhumbler, 1911, an organic-walled foraminiferal species that inhabits the empty shells of planktonic foraminifera and has not been reported since its initial description more...
