King Crabs have begun to invade parts of Antarctica, causing serious problems for the local mollusk inhabitants. Until now, Antarctica has been an environment that king crabs have stayed away from. Why? Because it was too cold. Not anymore. The temperature int he Antarctic has risen, meaning the crabs are able to survive much better, and since there is plenty of mollusks to much on, they have taken over. According to the biologist in the article, the Antarctic ocean in these parts hasn’t seen King crabs from nearly 40 millions years. That’s a huge stretch of time to not have an animal present only to have them come now. Obviously global warming is having an effect on these animals to make them move to a habitat they haven’t lived in for millennia.
