Could we leave these animals out in the ocean please? I know that there will be people that want to eat them because it gives them some kind of superpower you‘ve never heard of. But if you look at the year 2020 you may know that wild species can give you wild diseases. Or maybe we just limit interaction with these species only to scientists ghat know how to handle them.

It does, generally on islands: https://en.wikipedia.org/wiki/Island_gigantism Humans tend to exterminate them.
I think that’s an over generalization. The La Brea tarpit types were extinguished due to climate change. It’s also postulated mammoths and such were also affected by climate change, food availability and hunting. None the less, before humans came on the scene large animals came and went.
Of course if they had survived to even antiquity, yes, we’d probably have hunted them to extinction.

#13This might be a relative of our pill bugs? But there is probably a lot more evolution between them than between, e.g., horses and sharks. Which, by the way, is also bigger than between bony fish and sharks.

#14> The new giant isopod species was described from two specimens, ... 950 and 1,260 metres, during the South Java Deep Sea Biodiversity Expedition 2018
If you skim-read the article, you might end up with a very different picture in your head.

I'd expect giants to be more vulnerable to changes in the ecosystem. A new species is introduced that creates competition and the giants can't adapt to a new niche.
I imagine deep-sea is an ecosystem that doesn't get disrupted often. Little new introduction of species. Little human intervention.

They're still pretty big, but not destroying Tokyo anytime soon.

And also in environments with high oxygen concentration. At one point dragonflies were the size of cats (the cause is different from deep sea gigantism).

#18Earlier quoted context omitted.
I've always been fascinated by pill bugs, also known as "Armadillidiidae" [1] they are such cool creatures. I don't know why, but the fact that they are land-dwelling crustaceans was just interesting to me. I had no idea something like this size and related existed in the sea! Incredible! I wonder now what the evolutionary tree looks like. [1] https://en.wikipedia.org/wiki/Armadillidiidae
Order Isopoda [1] on Wikipedia if anyone else is interested. Edit: Corrected Family -> Order - oops! Thank you pvaldes. [1] https://en.wikipedia.org/wiki/Isopoda
Isopoda is an Order. This is in family Cirolanidae, so it has much smaller cousins in each beach.
It seems there is an opportunity here, crouching like a cat, to dedicate one of this new species to Hayao Miyazaki. Bathynomus ohmu seems an pretty convenient name also. Maybe the next.

#19I'm kinda disappointed, these aren't much larger than the giant isopods that you can buy at a well-stocked Asian grocery.

You missed an important part of the sentence:
> collected off the southern coast of West Java in Indonesia, from a depth of between 950 and 1,260 metres
the specimens were not 1km long.
