Molluscs on the move

Looking at the small stuff today. These sea plants and molluscs are under water (about 6 inches of it). Was focussing on the big one and then found later that there were more.

Did a bit of snorkling while Ruby guarded my towel. She doesn't have to but has given herself the task of doing that while I'm in the water and after she gets tired of swimming alongside. Didn't see much of interest... a couple of fishes swimming by but that's all. Hoping very much to find a nudibranch again. Found one just before Christmas but it was too way out to go back and get the camera. A fascinating and very colourful creature it was too.
