Giant crabs make Antarctic leap
By Richard Black
King crabs have been found on the edge of Antarctica, probably as a result of warming in the region, scientists say. Writing in the journal Proceedings B, scientists report a large, reproductive population of crabs in the Palmer Deep, a basin cut in the continental shelf. They suggest the crabs were washed in during an upsurge of warmer water. The crabs are voracious crushers of sea floor animals and will probably change the ecosystem profoundly if and when they spread further, researchers warn. Related species have been found around islands off the Antarctic Peninsula and on the outer edge of the continental shelf. But here the crabs (Neolithodes yaldwyni) are living and reproducing in abundance right on the edge of the continent itself.

I have often thought that a big crab like this was responsible for the Hilbre creature report :
