Unidentified Saltwater object

[Henchman24]

I found a white spiral looking deal on some of my live rock a few weeks back. I don't know if it is like a worm or something? It hasn't moved but seems to be growing.

I guess it is snail eggs. The images I found online of snail eggs have the exact same pattern & color. I guess it didn't grow but I thought it did as the live rock it was on was facing against the back of the tank & when I turned the rock around to take pictures it was way longer than I had seen before. I think the chance of survival is low on these eggs? Thanks for the help everyone
