The run of fresh episodes of his docu-series is to premiere next year.
"I'm excited to travel the world and continue to tell stories about the rare and beautiful animals we share this planet with on Season 2 of 'Wild Things,'" Monaghan said in a statement. "Thanks to all the fans and to BBC America for all their support on a project that means so much to me."
"The first season of 'Wild Things with Dominic Monaghan' was an amazing thrill ride that introduced viewers to fascinating rare creatures and exotic locales, and we can't wait to set off on new journeys with Dominic," said Perry Simon, the cable television network's general manager. "His vast knowledge of these animals and infectious enthusiasm make him the perfect host for this signature BBC America adventure series."
