Ocearch expedition hopes to solve puzzle of great white sharks
Ocearch fishermen and scientists tagged a great white shark named Hilton in March last year. Now they hope Hilton can answer key questions about the mysterious predators. The team has studied its trips to Nova Scotia, and researchers will go there for the first time on their 33rd expedition. They believe the area is a second mating site for Atlantic white sharks. Ocearch founding chairman and expedition leader Chris Fischer joins "CBS This Morning" to discuss the life cycle of sharks and what he is expecting on their upcoming expedition.
