109. The distribution of these groups formed a clear pattern with areas in the south-west of the zone dominated by group D and the northern part of the zone dominated by group F. All communities in the East Anglia THREE site were group F whilst the offshore cable corridor supported groups D and B (Figure 10.10).


10.5.3.2 Epifanal Communities within the East Anglia THREE site 110. Within the East Anglia THREE site brittlestars were far more dominant than they were across the East Anglia Zone (Diagram 10.9 and 10.7). They were present in all trawls with abundances ranging frombetween 30 to 186. The class Malacostraca comprised a very similar percentage of the individuals identified across the East Anglia Zone as they did within the East Anglia THREE site whilst polychaetes were relatively more abundant within the East Anglia THREE site than across the East Anglia Zone.
