Snorkeling fun

Earlier on in the summer, I discovered snorkeling! I had never really got on with this before, I think I kept going too far below the water and then breathing in the water, plus it doesn't really work with glasses and Royston swimming pool isn't a very inspiring place to do it! So basically me and snorkeling never got on, that is until now. Armed with contact lenses, the Mediterranean sea and making sure I didn't swim too deep (I found keeping your bum out of the sea helps) I gave it a proper go and really really loved it. Here are some things I saw. I have no idea what the last one is but wouldn't it look good next to this one?
