To answer this, we need to know what is this source of all organic matter (this name is probably not accurate to describe this, but it's the only name given within the SnK universe that can approximately fit this creature. Hallucigenia' is a good name tho, even if it's not an hallucigenia).

We don't know what it is. We don't even know if it's unic or not (there might still be other specimens). We can't even tell if it's really a living being. We don't know how it appeared/was created/was born/etc...

I don't see anything in the SnK universe that prevent another spinelike creature like this to exist, but it's pure speculation.

If you want, here are some reddits subs talking about it :
