I love how wacky nature can be. That 'living rock' threw me for a loop - I've never seen anything like it and was really hoping I was not in fact looking at a living thing that had been split in half. But either way, thanks for the insight into some crazy creatures.
Some I got close (I figured the underwater crop circles were made by worms not puffer fish) but the only one I got dead right was the wobbegong, if only because I already knew what they were. All interesting though. I could watch that Pharaoh's Serpent thing all day
