Changed Climate Blamed for Barracudas Settling in Colder Waters

Climate change is usually thought to bring hotter weather, but scientists say it can also make some places colder. Temperature changes mean some plants and animals struggle to survive, while others seek new territory. That may be the case for one species of barracuda that is living in colder waters than it normally would. A school of them have settled near an island off the coast of Croatia in the Adriatic Sea. VOA's Deborah Block has the story.
