this is a weird one. discussing with a few folks and current theory is that this is batoteuthis skolops, a really obscure chiroteuthid from antarctic and subantarctic waters, notable for having strange tentacle clubs (missing in this individual) and a very long, tapered mantle fin
Maybe Gonatus, but this one looks weird. @schmidtocean.bsky.social dive 867 #asgardarchaea #MarineLife

I've written a post about a tiny monster, a copepod which is monstrous by name and by nature.
It has no mouth and it must mate. As a juvenile, it lives in the body of a worm, and when it reaches adulthood, it pops out like a tiny xenomorph.

So, an "equal basis" of testing nuclear weapons with Russia and China is probably about what we're doing now with some advantages (eg, access to fusion burn)...
