Looks like stretch marks.
Ha. Kinda does. But yeah, that's a pellicle allright. I'd say you're in for the long haul. ![Grin ;D](http://www.homebrewersassociation.org/forum/Smileys/default/grin.gif)
I've got an IPA that will be ready to transfer soon so I won't be short on beer.
A little over a year ago I made an IPA and while chilling the wort a sudden burst of rain fell that caused some sort of growth during the fermentation. It looked like a jellyfish sort of, I thought that was a pellicle but now I'm not sure it was. Either way the beer tasted good.

It sure was a weird looking
creature though...
