[2] These elements are created within the cell and then assembled on its surface in a more or less regular arrangement, giving the test a textured appearance.

There is a single opening for the long slender pseudopods, which capture food and pull the cell across the substrate.

Euglyphids are common in soils, marshes, and other organic-rich environments, feeding on tiny organisms such as bacteria.

However, genetic studies instead place them with various amoeboid and flagellate groups, forming an assemblage called the Cercozoa.

In Placocista, where a few species have colonies of symbiotic Chlorella living inside them, the relationship is less intimate.
