Foraminiferans - Protozoan

Foraminiferans are largely benthic marine species. They have multi chambered calcareous tests or shells with numerous pores, hence the name foraminifera or pore bearer. A single large opening allows the cytoplasm to protrude out. The chalk cliffs of Dover England are formed from deep sediments of foraminiferan shells.
