It was larger than the flat part of my flipper. I've seen goosefish in aquariums before, but never one that big. We swam over a cusk, a large fish that sort of looks like a really fat eel. We saw a couple little cod and lots of sea pearch. On the way back in from one of the dives, we swam through a large group of sea gooseberries.
Sea gooseberries are tiny, clear, harmless jelly fish.
The lobsters were quite plentiful, and there were some large ones. There were lots and lots of very large crabs. The entire bottom was covered with huge sheets of rock. However, I don't think I saw more than a couple of square inches of bare rock. They were completely covered with sea urchins, ranging in size from smaller than a pencil eraser to as big as a softball, and gardens of sea anemonies of all different colors and sizes.
