Black sea supralittoral rock

The rocky supralittoral zone (depth 0-5 m) where the upper supralittoral rock is colonised by yellow lichens and cyanobacteria such as Lyngbiasp. and the lower supralittoral rock is colonised by encrusting black lichens, littorinids, isopods and barnacles. In locations with freshwater runoff and where nitrate levels are elevated the rock surfaces may be coated with green algae and a film of cyanobacteria.
