Crocodiles instill fear in most people at any size. But crocodile conservationist Romulus Whitaker fears that the most colossal of these creatures might no longer exist. Rom suspects that human hunting may have selectively killed off crocs surpassing 20 feet in length. In Supersize Crocs, Rom takes viewers along as he sets off on his own hunt to find the last of the leviathans. NATUREs Supersize Crocs airs on PBS Sunday, September 14 at 8 p.m. (check local listings), part of the 27th season of the Peabody and Emmy award-winning series produced by Thirteen/WNET New York for PBS.
