 Where 
            seen? 
            This black sponge that resembles antles is sometimes seen on our Northern 
            shores, growing on hard surfaces, including pipes and abandoned drums 
            near the mid-water mark.
 
 Features: Sparsely 
            branching 'stems' (up to 20cm long) that are cylindrical thick (about 
            3-4cm in diameter) with a smooth surface. Some branches taper to elegant 
            points. Also with low knobs. Holes at the top of knobs, and along 
            the length of the 'stems'. Colour usually a deep black, but when exposed 
            out of water may be greyish.
