Check out the Official Trailer for Underdogs, a new nature series dedicated to the animals that aren't quite at the top of the food chain, distributed by National Geographic.<br /><br />Each episode of the five-part series showcases a different aspect of these underdogs’ bizarre mating strategies, surprising superpowers, deception, dubious parenting skills, and gross-out behaviors. Underdogs features a range of never-before-filmed scenes, including the first time a film crew has ever entered a special cave in New Zealand - a huge cavern that glows brighter than a bachelor pad under a black light thanks to the glowing butts of millions of mucus-coated grubs. All over the world, overlooked superstars like this are out there 24/7, giving it maximum effort and keeping the natural world in working order for all those showboating polar bears, sharks, and gorillas. <br /><br />Underdogs is narrated by Ryan Reynolds.<br /><br />Underdogs premieres on June 15 on simulcast on ABC, and will be available to stream the next day on Disney+ and Hulu.
