- Loose boulders
Large boulders form a 40 degree slope down to a depth of 26 metres. With increasing depth, the boulders become increasingly smaller and interspersed across a mixed sediment bottom.
The boulders support an abundance of dead men’s fingers Alcyonium digitatum and anemones. There are a variety of hydroid species present, including Lytocarpia myriophyllum, Nemertesia antennina and Aglaophenia tubulifera. Several interesting sponge species occur here, including Lissodendoryx jenjonesae and Clathria barleei, both of which are listed as a Northern Ireland Priority Species and have only been recorded previously from the Maidens and Rathlin Island.
