Big, bad rodent sighted in New Jersey

Nutria are native to Brazil, Paraguay and Argentina. But they've been showing up in North America. A 20-pound rodent that scientists say is one of the world's worst invasive species has been spotted in New Jersey. Nutria eat vegetation, causing animals and fish to lose their habitats. State wildlife officials are asking people who spot nutrias to report them so they can determine whether they're colonizing in the state. Photo credit: Greg Lasley
