[1] Occultammina is an exceptionally large single-celled organism; like other xenophyophores it constructs a complex, single-chambered shell or "test" from sediment particles.

It grows in a net-like shape, the test consisting of hollow tubes that branch or form loose polygons.

The authors suggest that the relative distribution of radionuclides in the organism's body parts implies that it grows and excretes comparatively rapidly.

[5] The enigmatic "graphoglyptid" fossil Paleodictyon bears a passing resemblance to Occultammina, and this has led to suggestions of relationship between the two.

Paleodictyon fossils are known from sediments interpreted as representing abyssal paleoenvironments associated with turbidite deposits, potentially lending credence to the hypothesis.

The apparent absence of collected sediment particles (known as xenophyae) in graphoglyptid fossils further casts doubt on the possibility.

Staining of a second specimen did not reveal soft-bodied evidence for xenophyophores such as stercomares or granellae; some small agglutinated fragments were found that could have been from a psamminid, but this is not unexpected in deep-sea sediments.
