Remarks: |
A most abundant calcareous foraminifer in cold-water areas (temperatures
below 2°C) on the Arctic shelves; inhabits all sediment types; has
a complex pattern of distribution; often dominates foraminiferal assemblages
in extreme environments, such as low salinities, turbid waters, and low
food supply, including sites proximal to tidewater glaciers. Morphology
varies, possibly because of complex ecology, which has promted the discrimination
of several species by some authors (Gudina & Levtchuk 1989).
E.e.clavatum
tests are found in the deep Arctic Ocean, where they are believed to be
redeposited from shelves. |
