WTF is this? Alien worm?

I hope the videographer killed it with fire.

Found this in my backyard a week or so ago-

Ok, thats it. We're invated.

There were other small ones nearby- (1/2 inch-ish) I did wonder if they fell with the rain? (just got done coming down pretty good) I kept my dog outta the yard for the rest of the evening- just in case!

they are guessing its a ribbon worm.. i thought it might have been some kind of sea creature that had been put in fresh water, causing it to swell?

After looking at that parasitic eel yesterday I'm not looking at any more slimy, creepy-crawly things...harhar, they can't be unseen.

I've found one of those before took me forever to find out what it was lol...

"The nematomorph hairworm Spinochordodes tellinii is a parasitic worm whose larvae develop in orthopteran insects (grasshoppers and crickets). This parasite is able to influence its host's behavior: once the parasite is grown, it causes its grasshopper host to jump into water, where the grasshopper will likely drown. The parasite then leaves its host; the adult worm lives and reproduces in water.[2] S. tellinii does not influence its host to actively seek water over large distances, but only when it is already close to water.[3]

The microscopic larvae are ingested by their insect hosts and develop inside them into worms that can be three to four times longer than the host."

with the heavy rain its host must have died
