Roughly 140 different shark species lurk in the waters off the coast of southern Africa. The NATURE episode SHARKLAND, premiering on PBS Sunday, May 6 at 8 p.m. (check local listings), dives in and gets up close with the great white, mako, tiger shark and other fearsome predators, capturing dramatic ambushes, feeding frenzies and other remarkable scenes. <br /><br />Narrated by Academy Award-winning actor F. Murray Abraham, SHARKLAND is part of the 25th anniversary season of NATURE, the Peabody and Emmy Award-winning series produced by Thirteen/WNET New York for PBS.
