Both Crepidula fornicata and Aphelochaeta marioni, the species characterizing the biotope, are tolerant of a wide range of environmental conditions. For example, they are euryhaline, are found on a variety of substrata and tolerate variations in turbidity. However, they both achieve peak abundances in areas of muddy or mixed muddy sediments such as occur in the hydrographic regime of sheltered bays and lower estuaries (Gibbs, 1969; de Montaduin & Sauriau, 1999). The distribution of the biotope is probably limited by the geographic range of Crepidula fornicata, which only occurs in the southern half of the British Isles.
