An oral complex containing an aperture (an opening in the test) allows the filose pseudopodia to extend out. The pseudopodia are non-granular, and can form connections to make net-like structures. Gromia use their pseudopodia to crawl along the surface of sediments. Waste pellets (“stercomata”) and

Deep-sea gromiids have been found in the Arabian sea, off the coast of Antarctica and in the water of the Northwest Atlantic Ocean. They were often collected from the 1,000–3,100 m range. Oxygen levels in gromiid habitats tend to exceed 0.2 mL/L and are therefore not limiting to the

Gromiids are hypothesized to be important for carbon cycling, as they are often found in carbon-rich sediments and feed on detritus. In addition, gromiids have been shown to store high levels of intracellular nitrate, suggesting a role for gromiids in denitrification.

protists were later described in waters from the Arabian sea, the European Arctic sea, and off the coast of Antarctica, among other locations, and characterized both morphologically and through molecular studies of their small subunit rRNA genes.

Gromiids found in the deep sea near Oman and Pakistan are often found with Foraminifera, filamentous prokaryotes and bacteria living on their cell surface. Gromiids provide substrates and serve as a surface for attachment to their epibionts.
