Tide swept coarse sands with burrowing bivalves

What is it: 

Coarse gravelly sand on exposed coasts extending down to around 20m supports an abundance of burrowing bivalve molluscs, particularly Tellina spp. and surf clams, and polychaete worms, tanaids and sand hoppers. It has a very limited distribution with most records from Shetland and a few from Orkney, the west coast of Scotland and Outer Hebrides. Scottish records are probably of national importance at the UK scale.
