This has nothing to do with global warming.(likely)
This may just be a case of invasive species that has been carried in the larval stage from the arctic to the antarctic waters in the ballast tanks of
one of the many research or tourist ships.
There have been many cases of this happening with invasive species carried to the US so why not from the arctic to Antarctica.
This could even be a case of a county seeding the antarctic with these crabs to start a whole new fishery for there ships. (not as likely but very
possible) Australia, New Zealand. Japan or China
