it actually, may not be ascaris. I'm not sure, but Ascaris that i've seen, looks identical to a worm, if you saw this, you'd know it's a worm. those there, could be, but not sure. the 'skin' doesn't look firm enough. if you get more of them, see if they come apart easily, if they do, probably not worm. also those look almost bumpy at places, that's not Ascaris like either.
so, bottom line..i don't know, but it's questionable. i can say, if you pass a round worm intact, you will KNOW.
good work whatever it is, plaque, mucous or parasite...
