For the last 31 years, sharks have been subject to a week of media frenzy, taking place each July. But, throughout the year, they face a number of dangers that put their populations at risk.

Discovery Channel's Shark Week started Sunday and, this year, the focus is on conservation. On Second Thought dives in to explore shark facts, myths and more, from the Georgia coast to the islands of Palau.

The Georgia coast is a central calving spot for North Atlantic right whales; however, last year, no new calves were spotted there, and that caused great concern about the species. Only about 400 right whales are left in the entire world. 

Things are looking up this year: four, possibly five, calves have been spotted along the Florida and Georgia coasts so far this season.
