Description: Operational taxonomic unit (OTU): Crithionina ?’elongated’.
The test (‘outer crust’) is broken in these specimens. In the bigger specimen the incorporated sponge spicules can be seen. Macrofauna (sieved on 0.5 mm sieve).
Item Type: Image Title: Crithionina sp. Copyright: SERPENT project Species: Crithionina sp. Behaviour: deposit feeder Site: Atlantic -- Norwegian -- Dalsnuten Site Description: Seafloor Depth (m): 1452 Latitude: 66 deg 34' 33" N Longitude: 3 deg 32' 46" E Countries: Norway -- Norwegian Sector Habitat: Benthic Rig: Aker Barents Project Partners: Shell, Aker Drilling, Oceaneering ROV: Magnum 142 Deposited By: Dr K Kroeger Deposited On: 13 July 2011

Description: This is most likely the Xenophyophore Syringammina sp.
Xenophyophores are single celled organisms. The single cell branches and splits into hundreds of tubes which ramify and interconnect into a complex network. The test builds up as it proliferates, secreting a slimy organic cement. These are the largest structures produced by a single cell.

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.)

Sphaerozoum (sphere-owe-zoo-um), detail of the surface of a colony, in which many individual organisms can be seen. In the centre of each of the bright regions is the capsule. This is an example of one of the four types of large amoebae which is common in the marine water column. Dark ground image by Dave Caron.

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.

The typical chamber arrangement of this genus (planispiral in the early chambers, at the base, and biserial later) is evident here. Image courtesy of Elisabeth Alve, University of Oslo. Originally published in J. Foram. Res. 16: 261-284; used with permission.
