Chasing the biggest fish

A National Geographic project has scientists around the world studying the biggest freshwater fish and how we can ensure their survival. It's not even clear we know all fish over 6 feet (1.8m) long, the project's basic size criterion, and even less clear whether we know just how big some of them get. This article profiles the search for a freshwater stingray that may be over 4 meters in "wingspan."
