Great. Are these parasites.

I've not seen anything like that before. If it were me, I would go to a professional reptile vet, and then see if they can do a poop sample on it to see if any parasites are detected.

If that snake is housed with the others, I would remove it immediately and put it into quarantine in a separate room (tub and everything disinfected before putting it back in the rack). You dont want your other snakes getting what he has.

This is what I'm thinking as well, on all counts. I couldn't reach the vet earlier when I tried, but I will try again Monday as they closed a few minutes ago.
I couldn't find anything remotely similar on Google in the meantime .
