I'm a big fan of folklore SCPs. Let's see what you got.
Starting with the containment procedures and description. They read fine. I do feel as though you could invoke a slight bit more imagery into the appearance of these worms. I mainly bring this up because, without the picture, I really don't know what they look like.
The table doesn't really add any extra information that isn't already stated in the description, other than XXXX's ability to transmute itself. I think you could potentially scrap that section and move the blurb about the transmutation ability to the description.
Your writing is pretty succinct and clinically good. I could tell you went for brevity on this, though it may be a bit of a detriment which I'll get into later.
Yeah, this is pretty interesting and I found myself enjoying this. I just have a few concerns.
Firstly, this feels way too fast. I could tell you're attempting to build to something large here, especially in the GOC being there and the worms swimming to something. But there is a lack of tension here which is really killing it. That ending is really cool, but everything before happens too fast. It's a quick paragraph after a quick paragraph. I feel like the addition of an exploration log in place of the addendum about the statue would be interesting, plus a bit more into the odd behavior the creatures exhibit.
Secondly, I'd like for you to delve a bit more into the surrounding folklore because it feels a bit esoteric as to its origin if that makes sense. If you hadn't told me, I wouldn't have an idea that this was based on preexisting myth/folklore.
I'm not sure if this draft includes a strong enough narrative
That goes back to my point on pacing, you could develop this way further than what you already have.
Hopefully I was some help, good luck!
