Colonial radiolarian several millimetres in size, living organism encountered during a blue-water dive in the Sargasso Sea off Bermuda by Peter Countway. The bright spots are capsules of the component organisms. This is an example of one of the four types of large amoebae which is common in the marine water column.

Collozoum, a colonial radiolarian, the bright spots being the central capsules of the organisms which make up the colony. Up to 5000 capsules may be present in a colony. These colonies are like long sausages up to several centimetres in length. The colony has a segmented appearance because the components of the colony lie in a matrix around large vacuoles or alveoli . This is an example of one of the four types of large amoebae which is common in the marine water column. Image by N. R. Swanberg.

Thalassophysa (thal-ass-owe-fie-sa) is a large radiolarian protist has a cytoplasm that is full of bubbles. The bright area in the centre of the cell is the capsule and within this lie most of the cytoplasmic organelles. The yellow colour comes from symbiotic algae living in association with this protozoa. The algae are dinoflagellates from the genus Scrippsiella - the same genus is also found in symbiotic association with the by-the-wind sailor (Velella). The light region towards the outside is the region of the axopodia. This is an example of one of the four types of large amoebae which is common in the marine water column.

Thalassophysa (thal-ass-owe-fie-sa), a spumellarian radiolarian in which the cytoplasm is very clearly differentiated into the condensed inner region contained within the capsule, and the outer frothy later. Numerous symbiotic dinoflagellates (Scrippsiella - which also occurs in the cnidarian Velella) can be seen as orange spots in the cell. 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 N. R. Swanberg.

-
Solitary radiolarian, with large numbers of symbiotic (intracellular) dinoflagellates mostly concentrated in two opposed regions, with central capsule surrounded by an extensive pseudopodial net. 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.

Spongostaurus (spong-owe-store-us) - a large solitary radiolarian with linked sausage-shaped arms, to give a star-like appearance. 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 N. R. Swanberg.

Each shell contains numerous large granules
