Urchins eat coraline algae. That is why it disappears where ever it goes. I'm lucky, mine only seems to have eaten off the rocks on the back.

You'll need to make a few more posts before you can post pics, I think the number is around 5 now. Urchins are great members of the clean-up crew, they eat several types of algae and will remove it right down to the base rock which may appear white. It's a good thing.

Mine eats coralline but by no means eradicates it. I wish it would eat more. I notice the white streaks/patches where it grazes, as well. I wouldn't worry.
