Phoronis psammophila lives in the soft substratum at depths ranging from the intertidal zone to 69 m, commonly between 0 and 10 m. Densities may reach 18,000 to 20,000 ind.m-2. This species particularly prefers a sediment structure mainly composed of fine and very fine sand fractions (58 to 93%), with a moderate muddy fraction (8 to 41%).
Phoronis psammophila is a cosmopolitan species: the distribution is represented below on the map.
