WARNING FOR THE SQUEAMISH. AIBU to freak out at this worm

[polkadotpjs]

Just eating oven fish and chips and spotted this horrific sight. I'm now trying not to hurl or Google. It was nice too before this sighting. WTAF is it?? Is it a worm?????

Cod worms are why I won't eat organic meat.

Ok. Head prickling now with the thought of basa being both dirty and wormy.
I'm off fish again and quite happy to be. What's a zombie thread by the way? I suspect not good so I apologise
