Amphilonche (amf-ee-lonk-chee) - an acantharean, the cytoplasm is attached to the radiating spicules by contractile myonemes. Two of the spicules are much longer than the others. This is an example of one of the four types of large amoebae which commonly occur in the marine water colum. Dark ground image by Dave Caron.

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, has protuberances on two of its chambers (bottom), which distort the characteristic coiling pattern of the test.

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 its second-to-last chamber, at bottom.

This specimen, a dead test, has been in an environment that stripped the calcium carbonate away; only the organic lining remains. Image courtesy of Elisabeth Alve, University of Oslo. Originally published in J. Foram. Res. 16: 261-284; used with permission.

This dead test has had some of the calcium carbonate leached from it, giving the test surface a rough appearance. Image courtesy of Elisabeth Alve, University of Oslo. Originally published in J. Foram. Res. 16: 261-284; used with permission.
