baby urchin???

[howdy20012002]

I was looking in my sump in my invert setup and thou and beyond i found a baby..smaller than a dime...pin cushion urchin.
Has anyone heard of urchins having babies?
It is alive and kicking and crawling all over the rocks..
Pretty cool
Anyone know anything on this? is it possible to look at breeding these more?
I only found the one, but didn't really look for any more.
Any info would be greatly appreciated.
thanks
Neal
