1110 - Sandbanks which are slightly covered by sea water all the timeDescripción original en inglés (EUR28)
Sandbanks are elevated, elongated, rounded or irregular topographic features, permanently submerged and predominantly surrounded by deeper water. They consist mainly of sandy sediments, but larger grain sizes, including boulders and cobbles, or smaller grain sizes including mud may also be present on a sandbank. Banks where sandy sediments occur in a layer over hard substrata are classed as sandbanks if the associated biota are dependent on the sand rather than on the underlying hard substrata. Slightly covered by sea water all the time means that above a sandbank the water depth is seldom more than 20 m below chart datum. Sandbanks can, however, extend beneath 20 m below chart datum. It can, therefore, be appropriate to include in designations such areas where they are part of the feature and host its biological assemblages.Especies presentes (EUR28)

B., Biocenosis of coarse sands and fine gravels mixed by the waves (III. 3. 1.) with association with rhodolithes (III. 3. 1. 1), considered determinant habitat in the C. B., Biocenosis of coarse sands and fine gravels under the influence of bottom currents (also found in the Circalittoral) (III. 3. 2.). It is possible to find a facies and an association which are determinant habitats for C. B.: the maërl facies (= Association with Lithothamnion corallioides and Phymatoliton calcareum), also found as facies of the biocenosis of coastal detritic (III. 3. 2. 1), and the association with rhodolithes (III. 3. 2. 2.), Biocenosis of infralittoral pebbles (III. 4. 1.) with facies with Gouania wildenowi (III. 4. 1. 1.), small teleostean which lives among pebbles.
