This is the final version of the article. Available from the Grzybowski Foundation via the link in this record.We describe a new agglutinated benthic foraminiferal species from the Pliocene of Hole U1341B drilled in the southern
Bering Sea during IODP Expedition 323. The calcareous-cemented species Karreriella perforata n.sp. is coarsely canaliculated,
with regularly-spaced straight, unbranched pores that are open to the test surface. This feature of the test wall is rare
among agglutinated foraminifera, and is interpreted as a morphological adaptation to enable survival in the strongly hypoxic
environment present in the deep Bering Sea.We are
