| Definition | Well-draining beaches of medium- to fine-grained mobile sand, often (but not always) well sorted. Occasionally, a small fraction of coarse sand may be present. The biotope generally occurs on exposed open coasts, but sometimes in estuarine conditions, supporting populations of the isopod Eurydice pulchra and burrowing amphipods which frequently include Bathyporeia pilosa and Haustorius arenarius. The degree of drainage appears to be a critical factor in determining the presence of polychaetes, with only Scolelepis squamata capable of tolerating the well-drained sediments of this biotope. This biotope has two facies: drying upper and mid shore sands, and highly mobile lower shore and shallow sublittoral sand bars. Where this biotope occurs in estuarine conditions, H. arenarius is often highly abundant. | |
