This 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.
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.
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.
> The team says that the discovery is an example of deep-sea gigantism
Are there theories about this phenomenon? Does this explain the historically atypical size of the dinosaurs? Why doesn't it continue to happen? For example, why aren't there giant robins (birds) or tiny ones? Is there not a single eco-system ever where this would be an advantage?
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).
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.
Well, sure, there are loads that died out before humans showed up. But of those that existed when we showed up, we have exterminated almost all of them.

Often it wasn't even hunting. New Zealand's various giant ground parrots weren't THAT delicious. We introduced invasive species which did the extermination for us, in that case (and many/most bird-y cases, at least).
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.
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.
I understand the sentiment to a point, but isn’t it essentially impossible to get diseases from deep sea isopods? If we should be exploring any unknown creatures, deep sea creatures seem relatively safe if you are aiming to avoid transmissible diseases.
Maybe I’m wrong. I don’t know much about this stuff.
These things are cool.
