(fôr′ə-mĭn′ə-fər, fŏr′-) also fo·ram·i·nif·er·an (fə-răm′ə-nĭf′ər-ən)

Any of numerous chiefly marine protozoans of the order (or phylum) Foraminifera, characteristically having a calcareous shell with perforations through which numerous pseudopods protrude. The shells accumulate on the ocean floor as sediment.

[From New Latin Forāminifera, order name : Latin forāmen, forāmin-, an opening + Latin -fer, -fer.]

The researchers were therefore surprised to discover that foraminiferan tests sampled from the Challenger Deep contained calcareous components, including the dissolved remnants of coccoliths, the calcium carbonate plates of tiny algae called coccolithophores, and planktonic foraminiferan test fragments.

Previous work on milkfish, crown-of-thorns starfish, pearl oyster, foraminiferan and sponge populations (Winans 1980; Nishida and Lucas 1988; Benzie and Stoddart 1992b; Durand and Blanc 1988; Benzie 1991, 1994) identified major currents crossing proposed dispersal routes as the reason for the genetic differentiation of the populations concerned.

According to Dr Chris Wade from the Institute of Genetics, "Using genetic data we have been able to prove that the planktonic species Streptochilus globigerus and the benthic - sediment living - foraminiferan Bolivina variabilis are one and the same biological species."

By counting the abundance of different types of foraminiferan shells in sediments deposited throughout the northern Atlantic during the Last Ice Age, other researchers have shown that polar Foraminifera had greatly extended their range to the south; the Gulf Stream must have then flowed more-or-less straight across the Atlantic toward Portugal, rather than northward, toward Norway.
