Allogromiida

False-color image of a foraminiferan (pink) rending and consuming a bacterial biofilm (blue). The dark area is the region cleared by the foram in approximately 12 hours. Species not identified.

Notice the distinctive "herringbone" texture of the organic test (the dark portion of the image). Part of the cell itself fills the upper right hand corner of the photo. Image courtesy of Susan T.

Bathyallogromia was found in deep water (1000 to 6300 m) in the Weddell Sea, off the coast of Antarctica. Both images are of the same foram. The left image has the focal plane through the aperture (the twin bumps on the left side); the right image has the focal plane through the nucleus (indicated by the red arrow). The cell is about 200 um across, and appears whitish in reflected light. Image courtesy of Andrew J. Gooday, Southampton Oceanography Centre.

The aperture is a passage through the foram's transparent test, and is the route that the reticulopodia take to extend into the environment. The aperture of this species is surrounded by a "collar" which protrudes from the rest of the test. Image courtesy of Andrew J. Gooday, Southampton Oceanography Centre.

This image clearly shows the prominent "collar" around the oral zone for which the species is named. Image courtesy of Samuel S. Bowser, Wadsworth Center.

This species has an organic-walled test, which is thin, flexible and somewhat transparent. It is visible as the hazy "halo" around the cell body. Image courtesy of Samuel S. Bowser, Wadsworth Center.
