Can Someone Identify This...

[Roger Southwick]

You're  right -- we didn't see those on rocks or sand, only on wood.

I can't imagine a fish being able to deposit eggs like that...  must be some type of crawling thing.  Anyone know how crayfish lay eggs?  I doubt it would be snails, since I've never seen any big snails in Wazee.  The egg blob is about 1/2" wide so it probably isn't a bug either.  There are some rather long, continuous groups of these things, so it's not a small creature.

Then again, maybe it's some type of colonial growth.
