A typical wall off the Isle of Skye plunging almost vertically to 60m and more. Here at a depth of 23m where there is still adequate light, invertebrate life flourishes. The yellow and white clumps are soft corals, Alcyonium digitatum, commonly called Dead Man's Fingers. The purple patches on the rock are an encrusting algae known as Lithophyllum incrustans. Although an alga, it has the consistency and hardness of poured concrete.
