Invertebrate dominated Marmara circalittoral rock

In the Sea of Maramara a number of unique communities occur on circalittoral rock due to the high organic load characteristic of this region. In the upper levels (10-30 m) of outflowing Black Sea waters a thick layer of Ophiurids occurs. In the lower levels (30-50 m) of inflowing Mediterranean waters a thick layer of Crinoids occurs. Throughout all depths (2 - 60m) a fragile layer of tubeworms (Serpulid polychaetes) can be found attached to rock faces.
