Climate change is making Cape Cod a Tiger Shark habitat

A juvenile tiger shark, typically found in warmer southern waters, was caught off the coast of Cape Cod, Massachusetts, by Nate and Nelson Rouette, experienced sport fishermen. The five-foot shark, which can grow to over 15 feet and weigh more than 1,400 pounds, was released after the brothers' initial shock. John Chisholm, a scientist at the New England Aquarium, attributes the shark's presence to rising sea temperatures, making Atlantic waters off New England more hospitable to the species.

Juvenile tiger sharks are historically rarer in northern waters, making this discovery even more surprising. Tiger sharks are known for their diverse diet, which includes fish, crustaceans, birds, and even man-made objects. While adult tiger sharks are more dangerous to humans, unprovoked fatal attacks are rare. The Rouette brothers' encounter with the tiger shark highlights the broader trend of warming seas causing shifts in marine life distribution, with other shark species, such as great whites, also moving northward.
