Urchin spawning?

Caught this guy in the act of what I think is spawning.



Going to hit the google machine but does there need to be more than one spawning? I have a few but only see this one in action and what are the odds with a skimmer running that any survive?

Yes it’s spawning and I don’t think they can reproduce on there own

Thanks. Did a little reading and it does appear it would take more than 1. I have five but only saw this one in action. Even if the others did participate looks like odds would be low. Eggs stay in the water column and then larvae can float for years before they drop. So not thinking anything would ever come of it even if they all chipped in.
