Excerpt from All About Sharks: A Complete Guide to the World’s Most Misunderstood Predator (Nov. 2017):
No sharks have lived in the Southern Ocean around Antarctica for thousands of years, but that may soon change.
The concern is that global warming will increase the average temperate of the Antarctic waters, making them more hospitable to fish and sharks in coming years.
The impact is already being seen in the Arctic, where warmer temperatures have led to an increase of salmon sharks, which feed on seals and sea lions, decreasing their populations.
