A re-description of Discoconchoecia elegans (Sars, 1865) (Ostracoda: Halocyprididae) from high latitudes in the North Atlantic
Discoconchoecia elegans (Sars, 1865) is one of the most frequently recorded species of halocyprid ostracods and specimens are collected in abundance from various latitudes throughout the world oceans. This species is often dominant or subdominant member of the mesopelagic assemblages. However, its b...
