Table 2. Organisms and structures made by organisms associated with the two xenophyophore genera studied herein. The specimens were seen on the exterior of the xenophyophore tests, except for the foraminiferan Spiculosiphon Christiansen, 1964, which inhabited the sediment around the tests. The TNS registration numbers for individual xenophyophore specimens and the sampling sites (° N) are given at the head of each column.
