The Pittsburgh Penguins have acquired Erik Karlsson in a blockbuster trade with the San Jose Sharks. Pittsburgh traded a 2024 first-round pick, forward Mikael Granlund and defenseman Jan Rutta to San Jose and a 2025 second-round pick, goaltender Casey DeSmith, defenseman Jeff Petry and prospect Nathan Legare to Montreal as part of the deal for the reigning Norris Trophy winner. The Canadiens got involved to make the salary cap work. The Sharks are retaining just over 13% what's left on Karlsson's contract. Karlsson is the first defenseman to be traded fresh off winning the Norris since Doug Harvey in 1961.

Scientists with the New England Aquarium found that nurse sharks returned to the waters off the Dry Tortugas, 70 miles from Key West, to mate for up to 28 years. They also found that the sharks' life span appears to extend at least into their 40s, rather than about 24 years as previously believed.

The U.S. is a major hub for the brisk trade in which the fins of as many as 73 million sharks are cut off around the world each year.
