Almost perfect conditions for our latest visit to Roa Island to dive in the Piel Channel.  Underwater visibility was about two metres max. but the bright sunlight passing through the water made for a vibrant and very colourful dive.  Under these conditions the quantity and diversity of marine life which makes this location so special is plain to see.  The depth range of the dive was about three to six metres below low water neaps, the substrate mainly boulders and cobbles with muddy patches between.  Many species of seaweeds covered the boulders, blue mussels and periwinkles were everywhere.  Butterfish, shanny and corkwing wrasse were also spotted.  In just a small area of about half a square metre on the sponge bed four species of sponge, five species of crab, anemones, worms, nudibranchs, hydroids and common starfish were recorded. After recording common brittle stars on the lower shore on a shore walk a couple of weeks before it was hoped the we might find some on the dive, but unfortunately this was’nt to be.  We look forward to our next visit on saturday 11th. August.
