BRADY BARR

National Geographic's herpetologist and the first person known to have captured all 23 living species of crocodilian. Over more than fifteen years he's hosted upward of a hundred wildlife documentaries — more than anyone in Nat Geo's history — traveling to 80-plus countries to study crocs and the world's most dangerous reptiles in their own habitat, driven by a simple belief: we can only save what we take the time to truly understand.
