Before I knew what to look for I had taken several pictures of different kinds of nudibranchs. Some of them look like little bits of coral debris. I now know better. They don’t look like much and they are generally small. You need to keep a sharp eye for different. This one I had seen in another picture somewhere so I knew to get some shots before my dive buddies disappeared from view. I can’t say how I know, but it just isn’t coral. Looking and finding is like playing ‘I spy.’ So when you actually come across one, it’s a fun find. They don’t move much and certainly move slowly if they do. You’d think they are easy to find. But no, it’s not easy at all. So even yesterday’s post had one very similar. I had taken the shot but didn’t know what it was at the time. I follow the thought, when in doubt shoot the image if the subject is different from what you usually see. It can be hard to know you got the focus right. With this image, I knew better and got in for a good close-up.
