Cribroelphidium poeyanum, an epiphytic foraminiferan from Twin Cays, Belize

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.)

Image of a live specimen of Elphidium excavatum, taken at Sapelo Island, Georgia (USA). Collected and photographed by Susan T. Goldstein, University of Georgia.

This image emphasizes the surface texture of the test. Specimen is approx. 200 um across. Image courtesy of Susan T. Goldstein, University of Georgia.

This juvenile has only a few chambers, but is already showing the prominent sutures of the adult foram. Sample collected at Hamble Estuary, Hampshire, England. Image courtesy of Elisabeth Alve, University of Oslo. Originally published in the Journal of Foraminiferal Research 31:1; used with permission.

This species of Elphidium has a more ovate and smoother test than most others in its genus. From Laguna Madre, Texas. Image courtesy of Pamela Stephens, Midwestern State University.
