Description: The white agglutinating foraminifera is Pyrgo sp. and the brown agglutinating foraminifera is Cribrostomoides subglobosum. The latter made made up about 98% of the sieved macrofauna samples (sieved on a 0.50 mm sieve) at Dalsnuten. Item Type: Image Title: Pyrgo sp. Copyright: SERPENT project Species: Pyrgo sp.

Foraminiferans living in polluted environments often show alterations in the morphology of their tests. This individual, isolated from a site in Norway which is contaminated with heavy metals, exhibits reduced chamber size in some of its chambers (notice that the test is not evenly rounded.)

Orbulina (orb-you-line-a) - light microscopic image of a living planktonic foraminifer showing the large, spherical calcitic shell that encloses a smaller more dense spiral shell attached laterally on the inside. Numerous spines radiate out from the surface of the shell and contain dinoflagellate algal symbionts that are enclosed by the foraminferal cytoplasm that streams outward along the spines.
