Calling all conservation heroes! Meet your favorite Super Heroes and learn how you can be a superhero for endangered species! Tigers, western lowland gorillas and ring-tailed lemurs are just a few of the endangered species who reside at Franklin Park Zoo and act as ambassadors for their populations around the world. Join us on Saturday, May 19 for Endangered Species Day to discover more about these incredible animals and ask questions directly to zookeepers. Guests will also have the opportunity to meet and take photos with MARVEL’s own Super Heroes, Captain America and Spider-Man.
