Ecology of Marcia opima

Main Ref.	Poutiers, J.M., 1998
Remarks	Primarily marine but also invades backwaters and estuaries (Ref. 105059). Found in protected coastal areas, with shallow subtidal waters (Ref. 348). In muddy and sandy substrates (Ref. 105057) where it burrows (Ref. 105059). Family is known to be suspension feeders, filtering planktonic algae and organic matter from the water (Ref. 348).
