Global warming may bring giant, voracious crabs to Antarctica http://apocadocs.com/s.pl?1288800360
Changing ocean temperatures may allow giant, voracious, predatory crabs to enter the unique continental-shelf ecosystems of Antarctica.
Research by scientists at the National Oceanography Centre in Southampton in the United Kingdom found that even small increases in water temperature due to global warming could bring king crabs into new areas.
King crabs are a popular food source. But historically they haven't been able to live in the high-Antarctic continental shelves, so the species that currently live there have not evolved to cope with them.
