These urchins show up here and there. Unlike the spiny ones, this one doesn’t look dangerous. No matter. Don’t touch anything. It’s a rule. Every time I brush something by mistake I pay later. I now wear a wetsuit just to keep the coral from giving me skin rash. I was late to start wearing one. But I swear by it now. Compared to other things on the reef this urchin is not a common find. And it hides during the day. So this urchin also can move about. There no eyes. So this appears an easy photography target if you find one.
