Urchin Reproduction

Does anyone know anything about urchin reproduction? My pincushion has been secreting a stringy white substance for about 10 minutes now. What do you think? Pooping? Reproduction? I managed to get my camera on the tripod and snap off some pictures but wont have them loaded until later tonight if I can get on again.

 

"Reproduction: Fertilization is external. Female Sea Urchins release several million tiny, jelly-coated eggs at a time. Eggs or sperm are released through five gonopores. As they develop, the tiny larvae (called the pluteus, which have bi-lateral symmetry) swim in the sea and are a component of zooplankton. It takes several months for juvenile sea urchins to form. The time from fertilization to a reproductive adult is from 2 to 5 years."

By the sounds of it my urchin won't be able to reproduce successfully alone, but it is making zooplankton lol. My skimmer is going nuts. I don't think I can even leave the house or it will overflow.

 

LOL...poor skimmer.... would of been cool if it was reproducing.

 

Here's the picture I promised.
