Animals Working Together

Social behavior like caring for our young, fighting off rivals, or joining a pack adds a whole other layer of complexity to the lives of animals out there. We dive into the amazing ways animals interact with other animals, live a day in the life of the Portuguese Man O'War, and learn how these complex social interactions go way beyond anything humans are capable of!
