Rock Pools - an alternative perspective!

The underwater casing for my compact camera had only been used in warm tropical waters until last weekend when I had the bright idea of using it inside rock pools in Pembrokeshire. It was a bit hit and miss as most of the time I couldn't see what I was photographing but I did get some good shots. I think the most surprising aspect was the vibrancy of the colours. Seaweed and the slow or static animals filled all the frames. Perhaps one day I'll do it and find a big crab or fish looking at the lens but I think that's unlikely! I'll have to get a book on seaweed now. I can identify the topshells and sea anenome but can't name the plants in the photos. Also does anyone know what the green blobs of jelly are on this red seaweed?
