At around 35m
deep the bedrock-slopes give way to narrow
bands of boulders embedded in sediments and loose cobbles,
which may be tumbled around during winter storms.
Dahlia anemones and solitary sea squirts
colonise crevices where edible crabs wedge themselves.
Large spiny starfish slowly glide over the boulders,
under which lobsters and curled octopus lurk. Beyond
40m open expanses of fine mud and sand blanket the seabed.
Stands of sea pens are scattered between the entrances
of prawn (Nephrops) burrows, which dimple the surface
of these soft sediments.
