Nate and Nelson Rouette caught a juvenile tiger shark off Cape Cod, Massachusetts, a species typically found in warmer southern waters. Scientists suggest the shark's presence indicates warming ocean temperatures linked to climate change, as juvenile tiger sharks and other marine species increasingly appear in northern regions.

A tiger shark, typically found in warmer southern waters, was caught off Massachusetts, signaling potential warming of the region's seas due to climate change. Scientists suggest rising ocean temperatures are making northern Atlantic waters more hospitable to species like tiger sharks and great whites, which are increasingly sighted in areas such as Cape Cod.

A juvenile tiger shark, a tropical species uncommon in northern waters, was caught off Massachusetts and released, signaling potential warming of ocean temperatures. Scientists suggest rising seas may be making northern Atlantic waters more hospitable to such species, with similar shifts observed in other sharks and marine life.
