What is this?

[bkushy]

Just noticed them in my tank with lights out. About an inch long. Clear/white. Appear to have many tiny legs and swim or climb the glass. Any help would be appreciated. Can't say I like them much.

Thanks. Great link. Looks like the first pic under the dorvilleidae heading.
