The announcement was made this morning during the Discovery Communications’ portion of the winter TCA Press Tour where Animal Planet held a panel for its new Whale Wars-type docu series, Battleground: Rhino Wars. In addition to solid ratings, Whale Wars, which has chronicled the efforts of marine conservation group Sea Shepherd against Japanese whalers, led to Japan suspending its controversial whaling operations. The series spawned a five-part spinoff, Whale Wars: Viking Shores, which aired earlier this year.
